Okay, so I actually installed 8.2 Beta 3 from CD, and now there is a plugins service, hallelujah. Interesting that the gui upgrade did not add it.
HOWEVER, while following directions on setting up the service, I try to upload the pbi, and I get a cryptic error at the top of the screen.
Interesting that unlike in the video, the dialog didn't ask for an SHA code. Is that why it errored?
I've retried it multiple times.
