Separate. Not entirely sure how it works but another user in thread brought it up, sec...
Skarn: Actually, no. e/OS includes MicroG, so even most app requiring Google services work just fine. What really doesnt't work is Casting videos to a Chromecast, and anything requiting Play Integrity certification like Revolut.
Thought he provided more info, but yeah. Chromecast just does not function cause its basically in google walled garden.
Not in /e/os far as i can see. Maybe in aosp somehow? Frankly, I am not exactly a fan of many of the decisions Murena made. They're motherfuckers about letting me do the things I actually want in the system, for example: just update my apps, dont notify me. I do not care unless you broke or can't update. But no, I have to dismiss every successful app update.
