The forum is completely unusable on the iPhone/iOS platform. This is disappointing as many people UAE their iPhone/iPad to use the forums.
In particular, the JavaScript floating photo window is not functional on iOS. But, more importantly, it is impossible to log in!
I have also tried tapatalk app, which previously was supported and it does work but no photos or images display.
Since all of the above did work on the old Style Forum technology this is truly a step backwards. In which case my SF usage has been nearly zero.
