Yes, in 17.1 wifi calling worked OK after enabling it (*#*#VOWIFI#*#*). In stock ROM it works also.
I also have a Mi A1 phone with Lineage 17.1, but wifi calling doesn't work on that either even though it is enabled. The message I get when making a call with no network signal is shown on attached screenshot.

Hey maybe it's unrelated to this specific ROM, but when I enable the wifi or mobile data after a long time (a few hours), the device starts lagging heavily for the next 5 minutes. Probably because all the apps want to do their thing asap. In this situation, the main UI thread is blocked and we can't do important work until these background tasks are done.
Is there a way to delay these apps a little so that the user can do what he wants without interruption?

Sometimes certain apps (for example LinkedIn, polish public transport app Jakdojade) lose the ability to access internet while the rest works just fine. Internet access can then be restored by a simple reboot. Any idea if it's a bug or I've got something incorrectly configured?

    This man is a legend, without him, this rom would have half of its functionality broken
    I have build a new version, just looking for some feedback before releasing it into the wild. Flash it manually and OTAs are configured so that they will work directly when a future version comes around. Here is the link: http://transfer.sh/zKJBjR/lineage-18.1-20210906-UNOFFICIAL-daisy.zip

    LineageOS 18.1 is a free, community built, aftermarket firmware distribution of Android 11/R, which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the changelog for a full list of changes & features.

    #include <std_disclaimer.h>
    * Your warranty is now void.
    * We are not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at us for messing up your device, we will laugh at you.

    What's working:

    Known issues:
    You tell me

    1. Download the latest build from here
    2. Download LinkBoi00's version of TWRP here
    3. Reboot to bootloader (adb reboot bootloader)
    4. Fastboot into TWRP recovery (fastboot boot twrp*.img)
    5. Do a factory reset in TWRP
    6. Flash the latest build of Lineage OS
    7. Boot into your new phone
    Most of us will want the basic functionality like Google Play, Maps and others, therefore I recommend downloading Gapps. You choose your own, but I recommend OpenGapps. They are among the few that can survive OTA updates. They do not yet have official R builds, but you can yet the beta ones that work fine from here.
    If you do this, I recommend booting into the new LineageOS first, then reboot to recovery, do a factory reset and then only flash the gapps.

    Lyceris-chan (most of this is possible due to him)
    The wider Android community

    Ending words:
    This is a follow-up to the Lineage 17.1 ROM that I was working on. You cannot just upgrade from it to this via the system updater, you have to go through the process above. As said before, this is mostly possible due to Lyceris-chan, go support him. If you have any errors or questions feel free to ask in the thread. As for official status, might happen, probably not, I don't have enough time to make the push. As for MicroG, I plan to publish a build too, keep an eye out on xda. If I failed to credit you, make yourself known.

    Old builds:
    If for some reason you need older builds, they can be found here: https://github.com/a-huk/otaserver/releases

    By no means is it mandatory, I do this because I find it interesting. But it takes a lot of time and also requires me to have a powerful server, so if you could spare some change, I would be grateful.
    Sorry, for leaving the rom broken and being away for so long. I had important deadlines at school and could no work on this rom. Sorry, from now on things should be much smoother, probably microg build coming in the next month.
    Latest OTA is out, Bluetooth is working and it has the February security patch. Feel free to tell me you got it.

    I have gotten Bluetooth fixed, selinux is enforcing. Building now to see if I can get WFD foxed as well.

    Depending on the results, new build with February OTA might be out today or tomorrow.
