Suddenly cannot move pieces in courses during review.

I suddenly cannot move pieces in "courses" (chessable courses bought on chess.com) during review anymore. It still works during other modes, e.g. analysis and play. 

I also cannot interact with the board in any way, e.g. when using the real3d pieces I can resize and move the board in other modes, but not in courses.

I tried using another system (pc and laptop), using another browser, using other boards/pieces, using the "app" instead of the browser, and using other courses (happens in all of them).

Any idea how to solve this?

Sounds like there might be a bug. I have forwarded the report to staff

Have you tried using a different board/piece style?

Thank you for forwarding it. Yes, I have tried using a different board/pieces/style. The board/pieces change, but I still cannot interact with it during courses.

Should be working now

You're right, it does. Thank you very much!
