I initially had a problem with the plugin not working after I updated to Adobe CC (Lightroom 5) but I will go back and check with the latest release of the plugin. What I wanted to ask though - when I exported before, the meta wasn't transferred to stash. I had to enter title, descriptions and tags manually. Is this a known issue?
I did the following and now it works. I don't know which part of this made it work so i'm posting it all: 1) I reloaded the plugin from the plugin manager 2) I went back to the publish setup and noticed I had no name for the service, so gave it a name 3) Authorized again. Notice it gave me a different code this time. Entered the new code. 4) Logged in and everything worked.
