I logged on the Elsweyr PTS, made a new character (Breton Necromancer), logged on that character, and began in the tutorial mode.
At about level 6 or 7, I decided I wanted to travel to the Daggerfall Covenant starting area and work from there. I hadn't yet talked to Abnur Tharn for the Rage of Dragons quest.
I went to one of the Wayshrines in Elsweyr and selected the Port Hundig wayshrine in Stros M'Kai. To be brief, I discovered that the game hangs on the zoning screen at that point. A number of attempts failed to complete; the zoning screen is displayed and never arrive in Port Hundig. I waited as much as 8 hours (overnight) and found the zoning screen still displayed in the morning. The only way to abort the hangup is to close the game (ALT-F4).
I discovered that this hangup happens with any of the 8 other characters on the PTS (copied from Live) when attempting travel to Stros M'Kai.
I haven't tested all of the other wayshrines in the game, but the 5 or 6 I did test are working; only Stros M'Kai so far is not working.
