Not sure what this is?Perhaps Google Play protect is the culprit.
I have it disabled by default so not sure if it's another existing restriction.
The OnePlus check-mark did not work on my OnePlus + LineageOS device.
So then I implemented the root/LineageOS check-mark, which should work on any rooted phone, I'd recommend to use that one.
I tried again after a reboot to be sure, still blocked from allowing notification (Restricted Setting) and Special Abilities (Restricted Settings). At least play protect is not throwing errors, but also on 13 at least I can not figure out in king is setting it as installed be the App Store or not, since the instruction on how to check do not seem to work on 13.
I'm going to uninstall and reinstall again after a reboot.
Steps I followed:
Install AA-AIO-Tweaker via KingInstaller
Open and Grant Root Access
Install Android-Auto-XLauncher-Unlocked via King Installer
Ensure that Zygisk-LSPosed is enabled in Magisk
Now I can not do this step: LSPosed => Modules => Check Enable module + Check Android Auto
Since I can not open Lsposed as there is no notification, I have EdXposed Manager I can access, which says it is not installed correctly yet the moduleLSPosed-v1.8.6-6712-zygisk-release. is installed and active in magisk:. I see the module for android auto, but can not enable it by default, I tried skipping the check and enabling and rebooting anyways, assuming that worked I've completed that step as well now, if not I'm confused as to why it is not working when the module is installed.
Install my modified screen2auto
I did white list in AA AIO tweaker and reboot as I saw elsewhere that is needed, and rebooted one final time.
Special Abilities now works as does notifications, seems like I went through a number of extra steps and am still unsure of the EdXposed Manager saying it is not properly installed when the module is enabled, but with skip check I can enable the Android Auto module.
