Do you know how long it's been installed? My wife's calyx had cashapp until she had to reset her phone. I would say about 8 months ago we couldn't install it any longer.  Unfortunately, places like apkpure don't keep old versions of financial apps, so I don't know how to fix it. We both use calyx on a pixel 7 and pixel 6. When you get your "new" phone I would be very intersted to see if you can use cashapp.
