totalCorrectCards has stopped counting—including on CL documentation of that source

Something’s not working the way it seems like it should.

When I … start correctly sorting a card sort with 1) an established answer key and 2) a subtitle sourcing totalCorrectCards, the count does not update until I navigate away from the screen and back again.

I saw … a 0 in the subtitle, despite my sort matching the answer key and no CL errors.

But I expected … the number to change while on the screen, and manipulating cards in real time. totalCorrectCards had been updating dynamically, without need of leaving-and-returning to the screen, as recently as last week.

Here’s the link to the page, dashboard, or activity … from Desmos’s own documentation about CL: Activity Builder by Desmos Classroom

And here are some screenshots or a video:

Console warnings and errors from Chrome v144.0.7559.111 on a Windows 11 Pro machine include

  • Uncaught (in promise) Error: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received
  • Error: Trying to update view that is not mounted

But the same problem occurs in Firefox, Edge, etc.

Thanks for this report. I’ll pass it along to our engineering team. It also seems unique to the subtitle: sink, as I am able to see the same string update in the title:.

Brilliant. Thank you so much, Daniel!

I wonder if Engineering can also check my sanity about how recently this started to fail …

Others have been noting the same thing today! So, I think it’s pretty new.

This happened earlier this week to my classes as well.

Same thing for me… I’ve used this cardsort check for years using subtitle on many different lessons, and today it didn’t work quite right.

When they are all correct, the message in the subtitle should immediately change. But today it doesn’t appear until kids go to the next screen and then go back.

The cardsorts are on screens 11 and 20.

This issue should be fixed. Let me know if you’re seeing any different. Thanks all!
