This might be better placed in the PPro or AE forums, but is anyone else having issues with Dynamic Link in CC2014? Whenever I have PPro and AE simultaneously open with a linked PPro sequence, Premiere becomes unusable. Only audio will playback, the CTI and video just remains still, and then the program is unresponsive for several seconds before finally recognizing my command to stop. Also AE has fits of giving me the spinning wheel from time to time, although it's not nearly as problematic as Premiere.
So right now my workflow is to work in AE, then if I want to do any editing, I have to quit AE, make my edits in Premiere, then reopen AE. On top of this, new edits in AE aren't recognized unless I ctrl+click the .prproj in AE's project window and click "reload footage." It's quite a pain.
