Yes I think we will do that - I was certainly always under the impression there was no impact. Thank you for your input!@Jaimie S - Ad impressions and GMB rankings are supposed to be completely independent.
Perhaps a quick test would be to pause your Google Ads and see if that changes Maps rankings. I would be surprised if it did. I believe this is just a ranking issue.
If it helps, I'm involved with a listing that dropped off the map, then recovered and then dropped drastically again, all over the last ~72 hours. Maybe others can weigh in on whether or not they're seeing this kind of turbulence.
