Crashes on my iPhone SE 2. Gen which was to be expected :-(

Crashes on my 13 Mini, which is unexpected! Anything we need to do to prep the phones?

I think that probably is to be expected, unfortunately. The model is 2GB; per the article iOS will kill apps that use 2GB on 4GB RAM devices (and the 13 Mini is 4GB).

It works just fine on my iPhone 12 Mini, which has (basically) the same RAM, so it seems like it's something else. They're basically the same phone in general though, so I would be surprised if it was a hardware issue.

It's running on my 13 Mini (so far).

I did have trouble closing the "adjustments" dialog (upper-right button) due to its close button being underneath the status bar, but found that I could just drag the dialog down to the bottom and it closed.
