Thanks for your reply.
It looks like most of the bugs were fixed with a Discourse Update that was released today.
I have update the original post to reflect the first 3 bugs which are not as a result of Air Theme.
The version which I am using now which fixed of the first 3 bugs, is:
Discourse: 3.1.0.beta3 (e014635a12)
Now that those bugs are fixed, all thats left is
Which is not a big deal at all. Although I still believe its a bug since Mobile View on Desktop and Mobile View on App/Browser (which should display the same) do not with the white #main-outlet style. I’m not sure which I prefer now. I’m happy with either outcome.
