Issues with mobile pop-up

On my site, the X button to close out the Pop-Up Wrapper text works just fine on desktop, but once it gets to the mobile landscape orientation, it stops working, and I can’t seem to figure out why. If you go into preview, click the Answer the Call button, and then click the X in the upper left-hand corner of the pop-up screen, it doesn’t do anything. Any idea what I’m doing wrong?

Did you happen to change anything on the project since posting the issue? I just checked on my end and the X button works just fine within the Designer preview window for the mobile breakpoint.

I did, yeah. I reverted to a previous version, which seemed to correct it. No idea what happened, but I guess I must’ve done something, which when I reverted, corrected the issue. Thanks for looking!
