Unable to undo with layered loops

[ScottHsuMusic]

Please describe the problem:

Updated to Chopin this week. I've noticed a couple of issues how the firmware handles audio clips, especially with udno. Here's one issue I've been able to reproduce.

When recording multiple audio loops in layered mode, I'm unable to undo loops as I'm looping. I also get locked out of being able to scroll until after the loops have played back. In this video, it seems like I can't even undo the clip any more for some reason and I need to manually delete it.

What is the expected behavior?

Undo works normally for layered loops in community firmware 1.1

When did you start noticing the issue?

Since loading 1.2
