Automation set up was.
Step 1: When a record matches a condition.
Step 2: It will update a field which is the "Client Portfolio Record" (this is a linked to another record field to a view called Client Portfolio)
This automation was just working fine before, but there was a change happened on the default column in "Client Portfolio view" which caused the issue.
If you suggest putting it back to the normal setup, I can't because the default column in "Client Portfolio View" which is the "Portfolio Title" should be in formula type now. It should also remain as default column.
Is there any way to update this automation even if the Portfolio Title is still a computed field?
