Problem solved, after 5 days Viber back to normal. I did not do anything, I updated ios14.4 but I dont think thats it, probably Viber team solved the problem
Ok, so Huston we have a problem AGAIN! I have iPhone 13 with ios 15.03. And everything you all reported is now same for me. Viber wont send pictures and all media, but i have no problem sending text. So what now? I have to wait for some new update?!
