Attempts to use the flag button don't seem to work on either mobile browser, nor Firefox desktop browser. Is this a profile level limitation?
It works just fine for me if you flag for abuse or spam. The report function is broken.
I think the flag option is too readily accessible. Having to first tap a menu and then to flag where it is not as visible and basically one tap will help stop some of the abuse we are seeing if it.
I feel like the flag button will be used like a dislike button because there is no down vote option. Unlike g+ where you at least had to give a reason why
