We used workorderID labels in our classic project to show the despatchers, the workorderID of an assignment at a glance.
After migration, the same labels from the assignments show up on the authoring maps the 'Dispatcher Map' but do not show up in the workforce project referencing the same map. A workaround is to add the assignments layer again and turn labels on on that layer and hide all the generic points so only the labels are shown but this is untidy.
I do believe it's a bug unless someone else has it working properly.
Thanks
