Was there an update today?
After several months of pretty smooth sailing, suddenly today our videos stopped working with one method and are continuing to work for the other.
This iFrame thing is still working great:
<iframe src="http://content.jwplatform.com/previews/8oU3jVMx-Re6FScHX?exp=1429000145&sig=e281b2a865e135895a0f5c95c5073a71" height="200" width="350"></iframe>
In this case the player will show the starting frame and then the loading animation runs forever.
Was there a change?
