This has been an ongoing issue for a very long time now. The forum report function does not work at all on mobile (IOS in my case). It brings up the report window, but has it formatted where you can't access the submit button at all because the window is bigger than what the phone's screen can access. (See screenshot below)
It makes it impossible to report any forum issues that may arise, and is a problem that has been around since the beginning.
I'd like to request this be changed so those of us using the mobile version of the ESO forums can use this.
EDIT: the image is just an example and the thread depicted is not one being reported by me.
