Hi @BLUEFROG. I’m trying to reproduce the shortcut you have shown us here but I am missing what’s going on inside the Update Item Metadata action.
Everything I’ve tried just overwrites the existing tag(s) on each repeat loop (so I end up with just the final tag on its own).
Update: I answered my own question. You just need to pass the list of tags as a list (not just as text) to the action field as shown here: List of feature requests for iOS (and future macOS) Shortcut actions - #9 by BLUEFROG
I thought I tried this but I must have been confused…
