It would appear that "guessing" moves is not working for me within Play. This post from 2 years ago describes the behaviour I'm getting: https://www.chess.com/forum/view/general/why-is-my-guess-the-move-not-working
However, like it describes, guessing within Live Chess works fine.
I find it strange though that this only started happening recently for me. Anyone else experience this or have a solution?
Make sure you have Lines toggled Off.

Hm, I see. I thought it was, but I'll have to double check.
No, Lines is already off, but guessing still does not work...
well try it
I've submitted a help request to the staff so we'll see what they say

Last two times I've checked it was working correctly, though I have both Lines and Evaluation off.
Update: It's working again 
Not really sure why... Evaluation, Lines, and Explorer all have to be off. Perhaps refreshing the page did it.
Scratch that... it worked for one game and now it's back to not working... 
That's exactly the behaviour I've had as well. I did have a few interactions with support, eventually sending them a video as well, but they never got back to me with a resolution.
The strange thing for me is that it's not a consistent bug. Like I mentioned above, it started working one day and then soon after stopped. Just now I checked, and it's working again. I thought it might work for only the first game, but I tried several and it kept working. Very odd
