We've been using a WorkApp to present smartsheets to users for a few months, with a 'my assignments' style filter, which have been working as expected.
However, over the weekend these filters have suddenly stopped working. When a user uses the filter, no items are returned (i.e. everything is filtered).
If the user opens the SmartSheet outside of the WorkApp, the filters work as expected, so it appears to be some issue with the WorkApps.
Does anyone have any ideas?
