I have a Mac Mini M1 running macOS 14.5 Sonoma. Until recently I was running iPadOS 17 on my iPad, and things worked just fine. I had the iPad setup so that it displayed its own stuff, but allowed my to operate my mouse on the iPad screen by moving past the left hand side of my monitor. This combined with copy and paste between iPadOS and macOS gave me a great workflow.
A couple of days ago I installed the dev beta of iPadOS 18 on my iPad, and seem to have lost access to all of the functionality described in the first paragraph. Can anyone advise of what I need to do to get it back, or is it just a case of waiting for Apple to re-establish the missing functionality in newer versions of the beta?
