Downgrading has led to locked boards.

Hi everyone, 

I was on a team plan for a year and had to discontinue my payment as the price has increased but the features and use is still the same. Plus due to financial budgeting for other softwares that I use.

I was on two teams,  I left one called C.E because I didn’t need to be on it anymore and hoping that the new team that I had created called M.T which was all my personal boards would be unlocked. 

But that is not the case. I am currently on 1 team( M.T) and all my boards are locked. 

How do I solve this ?
