I've had no problem with this but I recently had cause to change my facebook password. I upload photos to facebook from a graphics program (ON1 Photo raw2018) which uses the macOS Internet Accounts to do so. Since I updated the password on Facebook though I keep getting the above message - "Can't Connect to the account facebook". I have put my new password into the account several times, tried deleting it and re-entering all of the information (username and password), re booted the Mac and even tried deleting the oath tokens in Keychain Access>Passwords. All to no avail, it still won't allow me to connect to FB and upload photos. I can access FB the normal way so its not the FB end. Any suggestions please? I use a 2014 Retina iMac with latest macOS. Thanks in advance.
