The form, FormEditCell, is standard and has it's Item propertery set to: GalleryCells.Selected
If I click on the 'edit icon' on one of the Gallery records, it goes to the other Screen and loads the selected record as normal. However, if I click the New Record button defined above, and then click a Cancel button (OnSubmit = Back()), and then try to click an 'edit icon' on an existing record, it navigates to the other Screen but fails to load any fields/tables - the fields are just blank. I have to restart PowerApps studio to get it to load records again normally.
This is an app built on SharePoint lists. I'm 95% sure this was all working in the prior version (550?) of PowerApps...
Is this a real bug or could I be doing something stupid?
