I had 2 boards that were my main boards on the free plan. I upgraded my plan for a month and created a few boards which I ended up deleting and just use the 2 boards. However now that I have gone back to the free plan, one of my boards is view only. I only have 2 boards in my free plan. It mentions something about how it only keeps the 3 most recent boards but I deleted all my other boards and only have 2. Can someone help me change my board from view only or help me figure this out without having to upgrade?
