Quiz Becomes Unresponsive when Published

Hello again, Jerry!

Thank you for taking the time to share those extra details. I can't say I've seen the issue you're describing where glitches pop up as the file gets larger, but that's not to say there isn't something going on in your case.

I can understand how this is getting frustrating, so I'd love it if you could work directly with one of our support engineers. I've gone ahead and opened a case on your behalf and sent you a private upload link to share the troublesome file if possible. As soon as one of my teammates has tested your file, they'll reach out with the next step!
