I have a couple of my friends that are glitchy on both my FrankenPre and my Touchpad.

I know of at least two of my friends that are showing as "Add As a Friend", then when I click on it. I get an error, it says something like "communication error, you are already friends".

Yes, they are already my friends but the FB app on both devices does not seem to recognize them. Everything is fine when I look at the FB site online.

Any ideas what could be going on?

Thanks in advance for the help.
