WhatsApp Banned My Account Without Explaining The Reason, Request Recovery

My WhatsApp account on my iPhone 13 was suddenly banned yesterday between about 8 and 10 pm. When I tried to log in, I saw the message “This account can’t use WhatsApp.” I followed the instructions and requested a review, but I was later informed that I still cannot use WhatsApp, without any clear reason. I am not aware of breaking any community standards or rules. I politely request that my account be unbanned, or that I be given a clear explanation of the exact reason for this ban.
