Thank you for your reply and shedding some light on the matter, dbernal.
At the moment I believe I can get around without that field being present. However, I am considering adding, in the future, functionality that would require information about the checklists to be present and that might become an issue.
I think it would be a good strategy for you to inform our users that they are crossing the limit, when they are creating new checklists. Else, they have valid reason to expect, that their checklists can be fully processed by both you and custom Power Ups.
I am good for now and I will reach out if the new functionality will prove to cause issues, so we can brainstorm a solution, as you suggested.
Once again… Thank you for your help!
