Facebook bio is the little presentation area that gives others a thought of who you're or about your attributes. You can refresh the bio by going to the profile and altering it in the 'Introduction' segment. In any case, on the off chance that you can't do that, at that point this may be because of the helpless web association. You can understand this issue by going close to the wifi and take a stab at altering the bio once more. On the off chance that this doesn't help, them go to the Facebook customer service for more data.
