Yeah, sometimes it's like that in other apps and I almost double dap by default most of the time. But over the past few days there are times when it just doesn't work for some reason no matter how many taps. Sometimes reloading the same page will get it working and other times not even that.I find that I have to tap more than one for it to register. I'll try to keep an eye on it and see if I can pin down a pattern as far as page content, though that may prove futile.
It's been at a point of almost being 50/50, which is not something I've come across before on my iPhone and prompted me to ask about it.
