Just got an Atrix 2 and comparing conflicting behavior with another one right next to mine. I can't access Social Media / Facebook through the SM App. If I try to add my account again, (and log in) it says it's already there. If I delete the info and set it up again, and then try to access Social Media, it is blank and does not show my user name and I can't access FB. The little red icon is there to add an account to the blank page, but it says mine is already there, even though it isn't listed. Have deleted, rebooted, removed battery etc. The other atrix 2 had no problems at all with this, could this phone be defective or a defective app?
