FCPX 10.1.4 can't share to Vimeo
Finished making a video in FCPX and shared it to YouTube. All was well. Then I decided to share to Vimeo too. When it was done processing and uploading, the notification popped up and I clicked the "Visit" button. When it opened in my browser, I was on YouTube, not Vimeo. When I logged into Vimeo, the video was nowhere to be found. On YouTube, no additional videos had been added, just the originally uploaded one.
Tried this about 5 times with the same result, making sure I wasn't an idiot who accidentally clicked YouTube instead of Vimeo.
I'm stumped. I also tried duplicating the project as a snapshot and re-sharing to Vimeo. Same result. I tried adding a "New Destination" and re-entered everything for Vimeo. Same result. ***? I've been able to share to Vimeo in the past, countless times, with this very same version of FCPX. The only thing that has changed recently is that I installed iTune 12.1 today, and also recently installed Security Update 2015-001 and upgraded Logic Pro X to 10.1 (probably not relevant, but thought I'd mention it.). Could these have affected things?
