Hello
I have found that as of 32 minutes ago, my main board now has due dates added to all cards that previously had (purposely) no due dates, but now have 15.02.2019 00:00.
As soon as I remove the due date, it bounces back on again.
I did try adding and removing a few power-ups and hope that this has not triggered it!
Please help!
Many thanks
Graeme
