I am trying to maintain my administrator certification spring 22 and in the challenge section I have created a restriction rule as per the instructions, but I can't seem to activate the rule. It gives the following error
You reached the active restriction rule limit. To make this restriction rule active, first delete or deactivate one.
I only have one restriction rule on task object which I created as part the challenge in my trailhead org. I have turned off Salesforce Classic for your org to rule out that issue possiblity as well but to no avail.
