• Please copy/paste the error message you see on your screen, if any.

I'd say this is a bug based on attempt to repro since it first happened, but there isn't an appropriate "What happened" choice.
I had accidentally flipped to other player's board when attempting to scroll (on phone). I thought I saw a little flicker, but didn't think much of it. We are playing turn based over days and I didn't notice as other player's board is very similar.
I took a legal action based on incorrect state, then the magically a filled in cell wasn't because UI swapped back to my player board.

While attempting to repro on desktop, when clicking on card pair I see the board is flipped by to my player board.
Attempting to repro on phone again, I mostly cannot. First time I got an error bar. I think it said unsupported action. The next I was flipped to my player board. When then swapping to another's board before selecting cell there are not enabled cells to fill (as desired).
