The home of Phabricator/Phorge is just broken on mobile.
As far as I can remember, it just shows the menu:
{F272753}
But it's really duplicated:
{F272755}
So, you never see the contents. You just see the menu.
== What should happen instead ==
On mobile, the //menu// should be hidden, not the contents. So, you see the contents:
{F272756}
And, if you want, you can see the menu of course, as usual:
{F272757}

I set this as high priority, since this is a really boring issue, even if it's a long-term issue.
