My boards disappeared

[Jérémy Carpentier]

Hello, I'm a free version user.

I had multiple boards I was using; one was shared with another person.
After an update on Android, all my boards disappeared.

I did not delete them by accident, and when I try to look on the closed boards (on the web version of Trello), no boards seem to have been closed.

I used it 2 months ago, so I'm still an active user. I don't think my account needed to be deleted. 

I also saw that there could be an issue with the admin account, but I'm pretty sure that I was the admin account...

How can I recover my boards, please?
