I just started running Roon on a new iPad Pro (2018) 12.9 inch. It works well in landscape (horizontal) mode. But in portrait mode (vertical orientation) it always comes up in landscape. It’s the only app I’ve seen do this and very frustrating. My setup requires I mount the iPad in portrait orientation, and Roon is unusable.
Thanks for your feedback regarding this behavior. As @thyname mentioned, a ticket has been filed and is currently pending review by the dev team. I will be sure to let you know once it has been addressed in our next iOS update and I appreciate your patience while this occurs on our end.
I wanted to touch base with some good news and let you know that we’ve made some changes in Roon version 1.6 which should address this issue. Please update your Core + Roon Remote and let me know how it goes!
