I've been experiencing an issue that has causing me a lot of problems, as various apps including Whatsapp, Phone pay, paytm, youtube, galaery, and more will randomly log out, and reset back to their inital state as if I just installed it on a clean phone. Apps like Whatsapp and Telegram will have lost all of their chat history, even if it was backup up on iCloud. I'm at a total loss as to what might be causing this problem after restoring the phone multiple times (the last time without restoring to a backup). I m using iphone 13 pro max. I m from new delhi india.
