I couldn't post from an iPhone last night at all. It's usually wonky on the phone accessing the full site, while accessing three other Xenforo sites just has not experienced these behaviors at all. Last night it was over the top.
I usually post from an iMac and don't experience these issues, except for the repeated page reloads that Brad posted, which is also not endemic to other Xenforo sites.
The primary difference to this site and the others is the number of membership, and number of ads. That's not a complaint, just an observation.
I had slight issues two weeks ago with posting and likes. I turned the phone off and restarted and have had little issues since. Tapatalk seems to work great for my needs.
maybe you should switch to an android phone. I don't have these issues at all on my android or my iPad nor my desktop or laptop ... well damn... I don't have these problems at all, y'all must be doing it wrong ;-)
Turn your Wifi off and restart your phone. Use your phone without the wifi on. My data usage dropped dramatically with my wifi off, and the phone operates much smoother and faster.
