Restarted course not loading

I recently restarted a course on the web site. But on the Android app, it was still showing as before. I deleted the course and re-added it, and now it won’t bring up any data, words or the ability to do anything with it. I can still use the course on the web site just fine.

I’ll tag @MemriseSupport and @MemriseMatty, maybe they can assist.
