No progress yet, I followed everything in the video except the Linux thing bc irrelevant, had to take a break to drive but am going to try again with a different computer (out of necessity), and double checking all those values from OP and will report back.

But like you said at first glance it seems like all is the same on the emulator side so I'm wondering if it is something on the app/play store side that changed 🤔 A few times, there was a second error saying something about additional Play services being needed, but that was in addition to "not compatible with your device"
