Hello,
I couldn’t have my guest user access the board without an account and since I didn’t want them to immediately make one, I decided to try the visitor option. However, once were cleared FireFox caches and tested on Chrome, I could see the person as a coloured oblong with an arrow, but the person couldn’t move around hardly at all. They could only move in a tight circle and act on objects in the area. They couldn't pan across the board like me (the admin). They had edit capability and was on a trackpad (tried two fingers and checked Apple trackpad setting, it was in natural). So I can’t figure out the issue.
Their macOS was up to date Monterey 12.4 and the computer is an older MacBook ( not Pro, not M1) dated after 2017 I believe.
