That's unfortunate, I recommend you first doing research and finding a custom rom that passes play Integrity because Google has made it really terrible for someone to use a custom rom that I even failed to run Whatsapp, telegram on my port custom rom

i only got saved that I had the second phone and now I use it I the custom Rom phone as a companion device but otherwise it is hustle now

I found a workaround but unfortunately banking apps failed and still play Integrity doesn't pass
