yore There's got to be a third scenario. For example, Tinder. The most common dating apps. All my friends use it. I use it. It's on all of my friends Play Store, but not on my Play Store.
However, if I make a new throwaway account verify with my phone number and then sign in to the Play Store, I find Tinder, though I can't download it because I have to verify my age.
I don't own a credit card, so I can only verify my age by sending a picture of my passport to Google, and that's f*cked up.
There's got to be a way to download Tinder on a GrapheneOS device without sending your passport to Google!
