So I am trying to upload multiple pictures onto facebook instead of doing it one by one since I have a lot but it wont let me. How can I do this, or can I even do that?
Make sure your Facebook app is updated to the latest version. I've tried uploading multiple pictures using my Samsung Android phone to my Facebook account and it does work.
Close the app and the re-open again or restart your phone. Then try again if the upload function on your Facebook now works. Let me know if it does. Good luck!
