as “popup” I was referring to the error that is caught by the pack when trying to send a wrong value to Google
There is no errror as google will accept anything you type in there.
Validation on the region doesn’t seem necessary if it’s too much data for the pack, just adding the field to be synced is enough for me. Can you get that added on the next version?
One other suggestion is to link the Groups and Contacts table in the pack. In Contacts, it could link to the formatted name for each group they are in. Ideally this would be editable for the 2 way sync and you could just add/remove them from groups using a dropdown.
I am considering it, and that might be pushed in the next release. There is a new release that includes state/region for each address group.
