I wanted to change my number and deleted WhatsApp and added a new number. Immediately after setting up I wrote two messages and was blocked because of spam. I wrote to support, but they left my account blocked. Immediately afterwards I tried to add a new number again this time but it said directly that I have to use an official version of WhatsApp. After changing countless settings, I have completely reset Graphene OS again. The error message regarding the use of the official WhatsApp version remained for the new two numbers. I finally tried my old number and why can this number be used with the "unofficial version of WhatsApp". Is there any solution yet?
