Using Samsung Galaxy Tab 2 10.1 wifi w/v4.1.1 ice cream & latest version of facebook. Got this as a Christmas gift & have never been able to post a status update to FB or share a post. I can comment on FB using tablet once a comment thread has been started using my phone 1st. Same goes for private msg. Must use phone 1st, then continue on tablet. Please help, this has been driving me crazy for months. I have tried uninstalling FB & reinstalling several times. Thanks for any suggestions.
