Classic Mobile app: ITIL role users cannot select 'Assigned to' for incident record.
Steps to Reproduce
test the scenario in OOB London / Madrid instance using the mobile app or $m.do :
1. Login a OOB London patch 6 instance as ITIL User
2. Open a new (or existing) incident record
3. Select assignment group = Database
4. Click the reference lookup icon next to Assigned to
Observation: No records found for the assignee
On the desktop version, 3 results are returned OOB
I can also see that the behavior is different in versions earlier to this. In Kingston, the same steps return 3 results.
The workaround here is to remove the reference qualifier from the assigned_to field by going to its dictionary record.
