Looks like i posted my previous post in the "other" topic, though it should have been posted here.Haven't been keeping track of this thread for some months now. I think i came across a post that stated the last version still doesn't have Netflix or casting working, but now i can't seem to find the post anymore. It's a good thing i found my Fire stick for only 19 euro, because otherwise it wouldn't have been worth the hastle compared to a Mi TV stick, lol.
Anyway, i have Netflix working via the Kodi app. It's a bit less flashy, but it works and that's the main thing. I followed this walkthrough and though it wasn't written for Android TV, most of the steps explained were close enough to how it was presented in order to figure out what to do. https://kodibeginner.com/install-netflix-kodi/
I installed the latest Kodi from the google play store, so no shady website had to be visited nor did Aptoide have to be downloaded.
Hope that helps some people who might be on the fence (or already made the jump like myself only to be disappointed to find out Netflix still isn't working 6 months later). For me Netflix not working was kind of a deal breaker, especially with casting also not working, so i'm glad now the Fire stick can actually be usefull.
I won't be upgrading/updating the OS unless either Netflix or casting has been fixed, i don't feel it's worth going through all that again for some minor improvements. I actually wanted to use the Fire stick as a genuine Android TV device, not as a tinkering hobby project. It now serves its purpose for what it is. I'm running Kodi/Netflix, Stremio, some local TV stations official apps (VRTnu, VTMgo, Auvio...) and Spotify. All works well. I'm thankful for the work that has been put into the OS, even though it would have been nice to have those extra features working. But for me, it does what it needs to do.
Unfortunately just one day after posting that, that plan went out the door.
As Lineage isn't an official ROM, i assumed i could just leave play store set to auto update for the apps i was using without doing any damage. Unfortunately the latest update of Stremio demands an account, whereas previous versions allowed you to log in anonymously. So i deleted and wanted to go back to the previous version. In the meantime i also deleted updates of the Android TV Home to get rid of the Disney+ recommendations on the homescreen (as i don't have Disney+ and don't like these pushy ads).
But after installing the old Stremio app, i had to install the add-ons again, and some of these add-ons have to be installed via the browser. This was no issue before, but now suddenly this did not work anymore. Upon trying to install the add-on (which worked before with the same app, same add-on, same browser, same Fire TV Stick, same Lineage OS...) now suddenly i get an error message ER_UNKNOWN_URL_SCHEME. Tried a different version of Stremio, tried 5 different browsers. No dice. I set the stick back to factory settings, no avail. Finally i decided to just go through the hassle of installing an entire new OS (latest version of Lineage), wiping everything in TWRP. So after some hours, i was sure this time it was going to work... but it didn't. Also strange that my Kodi install after wiping everything and installing the latest OS, automatically still had my Netflix add-on installed automatically... How is that even possible? I know i wiped data and cache before installing the new OS. And still the same error remained and is keeping me from installing the Stremio add-on. Even when typing the line of code in Stremio to fetch the add-on externally, does not work. I have no idea what is causing the issue. It worked when i initially flashed lineage OS the first time.
Luckily i got Netflix working through Kodi, so Stremio not working isn't such a big deal anymore, but if someone knows what the problem is, please let me know.
As for the latest version of Lineage, i thought there was talk on page 1 or 2 to include an overscan setting in the next update (especially handy for old tv's that don't have that setting on the TV side), but i did not find this feature in the latest version. The audio/microphone search works, but you have to keep pressing the button.
