Since updating to iPadOS beta3, last night, I am unable to load files via Files app or Files API enabled apps. I first noticed it in 'Reality Composer' where I couldn't load previous projects, i'm also unable to create new projects. I tested 3rd party apps like Soulver and they suffer from the same problem.
I also tried restarting the device a number of times but to no avail.
Any thoughts on how this could be fixed would be greatly appreciated...
