Submit test button not working - attempts still available/delay in response

[CRMJ]

Thanks - first time posting here so I hope I did it correctly.

My test had 3 available attempts.  The first submission processed correctly, but when I completed the second attempt (answered all questions) and pressed the submit button, the test never submitted.  I reloaded the main test page, and it still only showed the first attempt. I again completed attempt two and the same thing happened after I answered all the questions - hit submit, and the button faded slightly and sat.  For many hours.  

Fortunately, I emailed my instructor and she accepted my revised answers for the two incorrect questions in the first attempt, so ,y grade was not impacted,

However, I submitted a CRITICAL help ticket to Canvas support and did not receive a response for four days, and there was no resolution - they only asked my instructor for information!  How should this have worked and what is the issue with the support delay?

@CRMJ This community is fellow Canvas users like yourself so we don't have a direct connection to Canvas support to answer your bottom question.  I can assume that it might have to do with the support agreement your institution has with Canvas, or lack there of.   My institution pays for tier 1 support so we generally get answers pretty quickly.

As far as the issue you ran into, I would suggest making sure you are using an updated and supported browser:  What are the browser and computer requirements for... - Instructure Community  I have seen similar issues when people were using older versions of Safari or Explorer which are not supported.
