Well, I've started having the same problems now too....... sad panda
Checked at 7:30 this morning and looked like it was working normally.
Checked again at just before 9am and started having the same issue of not showing unread posts as others have described above.
Just jumped on the forum then and see 18 new unread posts going all the way back to yesterday at 8:11am
Phone currently showing only 1 unread post.
