I have the same issue. I have uninstalled and reinstalled the app twice and still the same problem. I am on IPhone 12pro. I have phoned QB and the person I spoke to said they’d email me a link to upload information regarding the problem but I didn’t receive any email. 
QB is the most frustrating software. I tried to attach files here and I got an error saying maximum upload allowed had been reached and it was only 4 photos of my screen errors
