Android app in landscape

I'm trying to install the Android app on an Android-based SIP desk phone and I can’t log in. The Hubitat logo is very large and I can’t see the buttons to log in or create an account. I also can’t scroll down. It looks like the app might only work in portrait but, this being a desk phone, I can't switch to portrait mode.

I'm using a Yealink VP-59, which seems like an excellent controller for Hubitat.

Any ideas on how to make it work?
