Another ‘bug fix’ update is now available for Projector.
I’m still working on fixing the following issues that are still seen when running Projector on iOS 14:
1) PowerPoint conversions are not as reliable as when running on iOS 13 and below
2) Some video files that worked on iOS 13 and below don’t work on iOS 14
So, I would advise to please steer clear of iOS 14 on your ‘production’ device(s), or at least keep one iOS 13 (and below) device as a backup if you want to run iOS 14.
