Older boards will be read-only according to your documentation. This sounds reasonable for the Free plan. My question is about the Standard plan.
Would a user be able to re-activate an old board once they create 3 new boards?
Would there be an option to choose which 3 boards are currently active (there is something similar at Miro)?
Here is the important part of the documentation:
If you exceed the three active board limit on the Free or Standard plan, your last three created boards will remain active. Any additional boards will become read-only, allowing you to view and access existing information but not make edits. This ensures you can keep working on your most important projects while managing your board usage efficiently.
