The only fix is simple purchase a new line because even if you change to the official WhatsApp the error will still be there because it's the account which is burned not the app ( your number or account is still under the banned list) APART FROM THE APP IT'S SELF ..THESE PHONES ARE ALSO AFFECTED "HUAWEI, VIVO, OPPO, some_REDMI," currently for those facing the issue even though you never used any moded version of WhatsApp, please consinder checking your device, if it's sales region is china 🇨🇳 , that's the issue WE'VE LEARNED A LOT SINCE EVERYDAY WE GET CLIENTS LIKE 4 WITH THE SAME ISSUE
The only solution is to buy another phone with a different brand you are using that's what saved me Changing from a different phone otherwise nothing this guy is saying will help you
Will Facebook ban me from Twitter next? If I don't want Facebook, but instead I want toebook, elbowsbook or fingerbook, will they ban me from all other books and say that I have to use their book?
