Reporting back - so, interestingly, changing the UUIDs did seem to work. I don’t know why, but thank you for the suggestion.
What I’m noticing now, and I think this was always the case, is that Pushcut doesn’t seem to “catch” the iBeacons when a good bit of time has past, until I do something to “remind” the phone. To explain:
If I play with the beacons in the Estimate app, all is good. But a day or two later, I am no longer getting Pushcut Notifications from the iBeacon related Local Triggers. If I open the Estimate app, suddenly I will get a pushcut notification. What was interesting - today, I noticed I was not getting any notifications (beacon related), so I opened up the Eddystone scanner app on my phone, and as soon as I opened that app up, I received a Pushcut notification for arriving near the iBeacon that is sitting right next to me.
I wonder if there’s an issue with my phone, not with Pushcut? FYI, I have restarted Pushcut and restarted the phone multiple times!
