Struggling to participate in researchers' surveys
Those using Qualtrics - which seems to be much favoured by major academic institutional research studies - remained stubbornly impenetrable for months. Then someone to whom I'd rehearsed the whole problem suggested changing browsers and lo! that finally gave me access to the latest survey I wanted to take.
I had looked online in case this system were notorious for incompatibility problems but didn't spot anything this basic.
So, if anyone has a Qualtrics-based survey to do, then don't try to tackle it via Microsoft Edge. Google Chrome works - at least for me.
