There is a performance issue when setting the FLS and filtering for object attributes. It can take up to 2 minutes to finish.
One or more of the following can occur:
"Loading Data...Please wait"
"Could not update value"
keeps displaying when trying to update the "Secure" field and setting the group associated with an object, e.g. Project or Idea object or custom object.
The APP logs do not show any error.
This is originally reported as DE61971.
When marking an attribute for FLS, the object cache gets refreshed and the query behind is executed multiple times. For larger datasets, it takes time.
The issue is resolved in the next Clarity version, targeted for November 2021.
