Photo uploading

I like many others can no longer upload photos from my Photo Gallery to Facebook. This used to be a simple operation,Click on the Facebook  symbol and it happened. What has changed?  I have read that Microsoft no longer support this function. Perhaps if this is the case you can explain why ? Every time I try to download photos the message appears; Video upload is not a member of permissions table(602)    Several messages say "The Windows team are working on the problem". But if you are no longer supporting the function how can this be true. I look forward to a possible solution or an explanation as to why this function has been removed if that is the case.
