Problem with iPad application

[B.a.f]

Sorry to post in this section but I have not found anything such as a generic forums section using the iPad application.
I am never using the web based bimmerpost site and following the last AppStore update, I have trouble with unread topics.
First, the "Mark all topics as read" button just mess up everything : if some topics were already read, a few re-appear as unread. Same problem when I refresh a forum draging the page down after reading all topics, some of them (allways the same) re-appear as unread.

The reason I specified I never use the web based site (to be honest the last time I used it is around 3 months ago), is because the last release is supposed to synchronize read topics between application and web site. This is probably where something went wrong...
