I reported that back when Universal was beta in the beta forum topic, and got a bit of help from bigwheel MovieFanPlex in PMs. nothing came of it. It keeps happening where the redirect doesn’t occur, so like you did you basically have to hit Enter or Go or → or Return because until you do that, it may be spinning but not actually loading a page (no X in safari)
This bug finally went away in the new transcoder preview. 
This bug being reported by the OP is what I reported in my own topic after seeing a dozen other reports on half as many topics. I couldn’t get anyone from the team to respond. AFAIK the solution for macOS <10.11 is to install 1.28.2 or older, but I never verified that.
