I'm having one problem. I bought Watch Dogs: Legion on the Epic store, it installed, I tried to launch and it updated UBI connect, then prompted for username and password, and I got the 'An Epic Games service is unavailable at the moment' error.
Then I tried launching Connect manually, and it logged in fine. No sign of the game in my library, so couldn't launch it from there, so I launched it from Epic instead. It quit my manually started Connect, and started it again. Login failed like last time.
