I can’t offer much detail except to say that the app is intermittently (but frequently) very sluggish and unresponsive. The UI will not appear to react to touches, and then after several seconds will do something. Switching panels is nigh impossible, scrolling in a panel is equally non-responsive. After it goes through the sluggish routine, the app will eventually crash.
This was happening on the public release of iPadOS 26 and the beta release of iPadOS 26.1
I was able to fix the problem for a short while by resetting the workspace from the settings app.
If there are any other details that I can provide, I’ll see what I can do.
