Chris Devers, writing about how Apple Photo’s “concert tagging feature” often fails:
This would be a lot less annoying if Apple provided some basic tools to help out here.
If we could edit the concert event tags, we could fix the problem ourselves. Alas, the tags are added (or not) automatically, and we have no way to control them. Better still, if we could edit the tags to note which artist was performing, that would also help, particularly for events where two or more names were on the lineup. If the software gave greater weight to geotags, that might help. Few events span miles, nevermind dozens of miles, so if the photos are of different places, they shouldn’t be grouped together as the same event.
