I've set the tag in-app:
`UAirship.push().tags = ["test-tag"]
When I go to send a test push, the tag shows up in my list of possible tags. So it's obviously being sent correctly from the device and registered with the site (this is on-device, not in a simulator).
However, the push shows an audience of 0 and the device never receives the push.
Where can I start debugging this? Am I missing a step somewhere?
