OK, everybody is responding politely to this tool but I’ll tell it like it is. Using a beta for live work is the height of stupidity. I’d guess dolphins have a higher IQ than people who would try to gig with a device running a beta OS. You get fired in the real music world when you don’t know how to manage your equipment on a gig.
And why be rude/threatening to the development/support people? It’s YOU that did something blatantly foolish. Get iOS 14.1 on your device and get back to work.
