Students Chromebooks are getting unresponsive pages, told to reload then wait or quit. Any help?
It might be useful if we could see your code. The only thing I can think of is if they were using something like infinite loops.
If this is a persisting issue, you could reach out to support@code.org with as many details as you can provide and see if they are seeing this in other places. I have recently experienced chromebook issues on other websites as well, but thought it was a district filtering issue.
