I was doing some freelance work for a client and I shared a board with them. When I left the project I transferred ownership to the product manager and left the board. Now I have started using Miro for something else I see it is still on my boards list and using part of my free board allowance. It seems I had created a “Team” called Annie Streater (not something I had realised I did at the time, I thought it was just my personal account) and all my former colleagues seem to be in this “team” and can access that board. I have a free account, I’m pretty sure they were using free accounts as well (this was months ago, I don’t know if they regularly use Miro). 

What can I do so that the product manager retains ownership but the board is not in my “team” anymore?

Preferably I would rather do something that doesn’t involve me having to contact them and ask them to do a bunch of stuff 6 months later, but if I absolutely have to I’ll ask her to just make a copy if she still wants the info.
