I dont use Facebook but there are other options such as Slimsocial and other 3d party apps if you need Facebook on wm10 Facebook on Windows 10 Mobile in 2019 - your optionsI'm still using a 950XL. I also have a 950. I'm not really looking forward to changing phones. I'm hoping a decent Nokia phone will be available whenever I have to switch, but I'm planning to use the 950s until they simply don't work anymore.
I noticed today that the Facebook app no longer works.
