Domain with Coded Values - missing value

[NormanAnderson]

I created a blank data set with 2 fields which have a domain with coded values. This layer was converted to a AGOL service. Tracking edits and restricted control were enabled. After a week of editing one of the users noticed a value was missing.

This is a very time sensitive project.

Can the missing value be added to the service in AGOL?

Exporting the data, adding the value and re-creating the service is likely not an option.

I have briefly reviewed AGOL help & this forum.

Plan 'B' - use a place holder 'ZXC' and manually fixing the error at the end of the project.

Thanks!

I think your best (if not only) option is exporting the data and fixing the issue.
