I am having this weird trouble with the stock Foursquare app. Whenever I checkin, it does not post to facebook, though I have enabled the "Check-ins" option on facebook in the myprofile/settings page.

But whenever I revisit the myprofile/settings page the toggle button on Facebook check-ins is turned off. This seems like a bug on Foursquare.

Anyone has the same problem?
