This is a problem at Vimeo's end which neither we or they can replicate. If you've watched the video all the way to the end and it sits with a spinning circle, press shift-F5 to reload the page, then watch the video again. You can change the speed to x2. There is not usually a way of skipping ahead in the videos.
If that doesn't work, then try each of these:
- Try in a different browser
- If you are using our app, try using a browser instead
- Clear your cache
- Close other apps (if using it on your phone)
