I have two Devices/Things (both Nano 33 Iot) and email triggers work perfectly on one of them but I get no triggers from the second. I have checked all the obvious stuff, like making sure my triggers are referencing the correct Thing and turning the triggers off and on. I checked Trigger history to make sure that the problem wasn't with gmail. History contains no entries for the second Thing.
All other aspects of IoT Cloud (data sychronization, OTA, etc) are working fine on both devices.
I recently swapped the two Devices by detaching them both from their related Things, then reattaching them to the other Thing. Sadly, I hadn't configured triggers for the second Thing before the swap so I don't know if that induced the problem or if it was already there.
Any idea what might be going on here?
