Restriction rule for administrator certification spring 22

Question

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.

Answer 1

Yeah, I was facing the same issue. In dev orgs, if you look at the limit allowed, it says 0 out of 0 active rules. This implies that you cannot create any restriction rules.

So I created a playground org for this and the limit was 0 out of 2 active rules which allowed me to create an active rule and complete the challenge.

Answer 2

I don't exactly know the reason but creating a new playground org and completing the challenge there did the trick.

Answer 3

Perhaps older playgrounds did not upgrade to Spring '23 and so the limit for them is zero. That could be why a new playground solves this issue.
