I have an AGOL hosted feature service pulled into my Pro project (Pro version 2.3.1). I have made some changes to the domain values. When I click in a field, the revised list is shown. I select a value, which shows in the field. When I move to another field, the value reverts back to the former value, and an 'Update table row' error box appears stating "Value doesn't fall within Domain: Options," yet the values are listed in the domain drop-down. I have poked around in the '...rest/admin/services....' code (update definition), but nothing I do rectifies the issue. Strangely, in a few select attribute fields, the selected value does 'stick,' but the majority of the attempted changes do not. When I open the Domains tab on the Ribbon, the domain name does not show, and I see a message that 'The domains for this workspace are read only.' I am trying to change a field value from 'Free' to 'No Charge,' which seems simple enough. Thanks in advance for anyone's help.
