We sincerely apologize for this inconvenience and are working to address it. Google is in the process of making major changes to the availability of their data API, which TubePress uses extensively, and unfortunately this is causing inconsistency in the availability of TubePress video galleries. We are close to rolling out a fix to address this and will let you know as soon as it’s ready. The fix will require a few minutes of action on your part, but we will outline the process and be standing by if you run into any issues. We expect to have the fix out by tomorrow.
