Why can't I post comments on Facebook anymore?

[AC Question]

cannot post comments onto facebook anymore - help needed

About three days ago, I suddenly stopped being able to post comments onto Facebook from my andoid tablet. Up till then I did this by entering a comment and pressing the enter/return key and it listed the comment in the discussion.

Then late last week this just stopped working. I cannot find any way to restore it.The same function works fine in my PC still. Just not on my tablet. It is a hudl2, unmodified in any way
