Okay, so I still can't post from my phone, which is my primary "knotting" device.
It's an Asus Fonepad, running Android 4.1.2. I usually use Chrome on it, but the default (Asus) browser doesn't let me post either.
What happens is this: I click into the input box and my keyboard pops up, but before I can type anything it disappears again and will not let me bring the keyboard back up. It will not let me click the input box again.
This is not a browser issue or a phone issue, as none of my other forum sites are affected.
Every time I want to post on TK, I have to screw around to get my computer to connect through my phone. It's a PITA and I shouldn't have to do it.
