iPad keeps asking for Facebook password

I already checked other posts in this forum, and none of the suggestions have worked. Even a post from Apple Support doesn't work.

I keep seeing suggestions to delete the Facebook app, but WHY do I have to delete an app does works perfectly? Why not fixing the bug that keeps asking me for my password? Is this a reflection of caring for the customer?

I want the problem fixed, I don't want to delete my Facebook app from my iPad. How can I fix it, or when will the bug be fixed?

Thanks.
