Right now I find movement...difficult.
Teleportation is clunky, at best. I tried tp'ing to a locale in the same sim I was in at the time, but the screen claimed I was tp'ing to a different sim (which I could not tell was true or not). Then trying to tp to a "safe" spot with little concern for load left me - I'm not sure. My avatar was not displayed, and the location on the screen was strange. I think things locked up so I just closed the app.
My avatar looks OK (when it's on screen!) - my mesh body and clothing and other attachments and so on look as I expect. Except anything showing skin is pretty much black. No texture, nothing. Just black.
I'm bothered that after your first log in, there's no login screen or prompt (username/password) when you open the app. It immediately connects after opening. Not good.
