I'm not able to do anything for at least a month or so right now. I literally had major surgery on Friday with my neck being broken in 2 places a vertebra partially removed, reconstructed, a double spinal fusion and so on... because my spinal cord and ask if the major nerve roots were severely compressed. So I'm not in any position right now to make changes to the forum for a while.
I also do not have a top button option when on my android phone. I use opera as my browser.
I'm loathed to go off and install new options at present because I'm looking at taking the forum over to the new XenForo platform in the near future and anything installed now will be lost on the new platform and not necessarily compatible with it either tendering time and cost lost.
A lot of what people are reporting here is platform dependent as well as version and browser dependent and on top of all of that orientation dependant as
@morning glory has pointed out.
My browser will give a browser (not CookingBites) related up and down arrow for quick navigation if the screen if flicked rapidly up or down. The button arrives on the right hand side momentarily around the middle of the screen. I can't screenshot it because it disappears when the screen is stationary.
A quick test has just shown that the top button option is there in the landscape view, not portrait which would suggest a resolution issue.
I can only say I'll look at it and see what can be done, but not make any promises at this stage. I'd rather save the money to purchase new features once we are are the new version of XenForo. Sadly the forum isn't active enough yet to be self supporting financially.
