Facebook Business Suite Issues

Hi everyone. I’ve seen one post about this issue but the reply was just “it’s not a iOS issue, contact the developer”.

Even if that is actually a issue from the developer it’s kind of weird that I had this same app on my previous iPhone 11 Pro Max, and on other iPhones from other persons and no issues. So maybe there are something wrong with iOS or maybe there is something that I can try besides erase the app or restart the iPhone. Cheers
