I am running it on my iPad Pro 12.9” M1 with no major issues. It’s running quite smooth and snappy. I mainly use my iPad in place of my MacBook when visiting client offices or working from a cafe, so usage skews to email (Outlook and Apple Mail), iCloud (Files) and the MS office suite. Otherwise I’ll use it for light content consumption in the evenings - Apple Music, browsing via Safari, Reddit via Acorn, and maybe some TV watching through Jellyfin/Infuse. The only crashes I’ve had have been Acorn, which both occurred on beta 2. Nothing since installing beta 3.
