Subject pretty much says it all, there's no way to log out when browsing the DC site using a mobile.
There used to be ... but only if I rotated the screen to landscape aspect, now there's nothing.
FHD, same as my computer monitor, so plenty of pixels available.
An idea, instead of "Greetings ????", perhaps just the user name followed by (Logout) ... that's pretty much what is there on most sites I visit.
I know the site is transitioning so more a question of why something that was there and is a rather fundamental item of most, if not all, websites has disappeared.
