Please help me how solve, i have two issues
1. Content apptoval status in gallery
2. lookup value by lower (User)
For,
1. I assume 'Content approval status' is a Choice column? If so, you may need to play around with a Dropdown for that column. Try watching this @RezaDorrani video here.
2. Use the variable getting set in your App OnStart but change this Set() function to
Set(glbUser, Proper(User().FullName))
Then
LookUp('Project Employees', Employee.DisplayName = glbUser, SAP)
