IPAD / IPHONE - CHROME
On the forum pages, averything almost works as expected...
Pressing ‘Mark all as read’ does what you expect..
BUT, if you have within that page, previously used the equivalent of ‘hold and /right-click/’ to open a link within a new browser tab, the behaviour changes!
After using that ‘open in a new tab’ feature - when you press ’Mark all as read’, it displays ok, but doesn’t work, so you need to press it ‘again’ to display a slightly !different! context menu (OK, Suppress...) - which does ultimately work as intended.
Odd but annoying.
