I ran into this yesterday at work, using work's account. Initially I tried in Vivaldi, disabled blockers, cleared cookies, restarted everything, hopped on one foot while rubbing my tummy, patting my head, spinning in a circle, whilst chanting, still no luck. I tried even using the dreaded chrome, much to my chagrin, disabled blockers, etc, it too failed. Had to go elsewhere to make the needed purchases for work.
eBay has had issues with captcha loops for years, and they keep popping back up. It's good at shooing away buyers and sellers, not just script kiddies. Perhaps it's time to find something more useful.
