Grey line on students screen

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

When a student views some activities on their phone/mobile

They see a grey line on the screen while editing

Here’s the link to the activity Sketching Rational Functions • Activity Builder by Desmos

And here are some screenshots from Chrome on Android

The Chrome app version was 94.0.4606.85 The latest at the time

Update: I’m removed Chrome and installed Chrome Beta version 96.0.4664.27 and the problem is “resolved” … or is it :thinking: I may have just unleashed a whole load more problems by using Chrome Beta and I’m fairly sure I can’t ask all my students to install Chrome Beta in order to use Desmos :frowning:
