I’ve seen another report of this issue earlier on a new iPad Pro 12.9” 2020 - where it will not display in portrait mode. I was wondering whether you guys are any further along to a fix yet?
I also noted that there is someone with a 12.9” 2020 model (A2229) that didn’t exhibit the problem.
If it helps my iPad Pro 12.9” 2020 version is WiFi + Cellular UK.
Model number MXF92B/A / A2232 which is different to the above example.
Please do let me know if you need anything further. It is still an issue which is also present when I connect to a different Roon core that I installed on my Windows 10 laptop.
Hoping to hear some positive news soon.
Cheers. Rory.
