Fixed this. Was a couple of problems. Problems in Composr, but also with an override you had.

Also fixed your chat system to not run in overlays via {+START,IF,{$NOT,{$_GET,overlay}}}
...
{+END}
around the JS code to load it.

Hi Chris,
Thanks fixing chat in the overlays.

I have just tried the notification fix on my iPhone 6+ and cannot see any difference.
In mobile mode the advanced window does not open at all and in normal mode it opens but I cannot scroll it.

Cheers

Hi Chris,
This has broken another area :-(
In mobile mode on our forums if you click the [...] icon it should offer you the option of a page to jump to. Instead it now just takes you back to the top of the page and does not bring a pop up.
It works fine on the non mobile version.
I think this fix is related to this.
Cheers
Ade

Ah, there was a separate problem on smaller screens. Fixed.

I also have made about 5 other layout changes to make it work a lot better for the mobile notification management.
