I don’t think this site is accessible for an ipad3, but I’m still learning it myself and not really sure. I had to download google chrome in order to be able to log on, my firefox browser didn’t want to work.
I’m finding the same is true for me when I try to go to a chat room. This website is pretty new, so their aren’t that many users yet. I’m hopeful that it will improve with time.
The meetings that I have attended will let you log in late, and I believe that’s pretty common. I’ve only been to one meeting, but the host person told me that people come late all the time.
Hope this helps!
