Udemy App gives blank white screen on 11 inch ipad pro – Udemy Online Video Courses Review

This app is giving me a blank white screen on 11 inch ipad pro. Works ok on my 12.9 inch ipad pro. Latest ios version on both. Running IOS 15.2 on both, tried deleting and reloading app, tried restarting ipad. Looks like it may be an app issue.
