Ok, I guess I was expecting some sort of form to fill in. But, yes, I can send an email 
Interestingly, I opened up Pro Tools Intro and loaded Groove Agent 5 into it, dragged the same pattern into a track, looped it, and then proceeded to change kits and instruments with no issues. I find this very surprising - Groove Agent 5 seems to be more stable running in Pro Tools than it is in Cubase 12 Pro??? I must admit with my recent outlay of cash on Steinberg products, I’m starting to feel a little tinge of buyer’s remorse. I really hope they can get this sort of thing fixed. I also see so many people complaining of crashes and freezing on the forum. ugh.
