Conditional Move Bug

When I tried to make a conditional move, (I was white and it was not my turn) I moved one of blacks pieces and that worked fine, then tried to move one of my pieces and there was a message that kept popping up that said 'Please make a move before making a condition, then reset the piece I just tried to move. It happens multiple times.

IDK

That happened briefly to me last night, sorted itself out shortly 

This has happened to me in the past, (but it's rare), and I think I reported it but it wasn't fixed.

I have never been to this situation to tell a solution 

I'd love to be able to make conditional moves in my daily games with app; it works great with the live games in app. 

This happened to me I think when the opponent made a move while I was creating a conditional variation. So it is true that I had to make a move in the game before planning a conditional move.

That usually happens when your opponent moves while you are making conditional moves.
