I took Tapatalk off of the forums because of all the problems it was causing. I put a mobile friendly skin on it called "proflat" instead. If you go to your UserCP and choose "Board Preferences", you can choose "proflat" as your "board style" and be able to view the forums in a very mobile-friendly manner without Tapatalk.
Well that would certainly explain why I've had no luck logging in via Tapatalk over the past few months!
Thanks for the info guys. I've changed to proflat for now and will give that a try and delete AM out of my Tapatalk app.
