yeah that seems to be from all the way in 2021 unfortunately. you may be stuck with the browser version :(

you can try looking it up on plexus to see if others have had success using that app

if you want to degoogle the only way to run some apps without unprivileged code (GMS/microG) is to use grapheneos & its sandbox compatibility layer. this is unfortunately only available on the pixels.

I also worry you won’t be able to use some of the customization options that the nothing phone 2 offers with its hardware when using a custom ROM. if thats something u care about.

I have the pixel 7a & have had essentialy no issues with anything for what that’s worth.
