I notice this issue on XF as well as other XF forums that I have. Installed PWA via Safari and everytime the app opens, it has a blurry top navigation that scroll up and down may resolve but not all the time.
Very annoying. Not sure if this is an iOS issue or not?
Found someone reporting similar issue.
