Your provider has nothing to do with this.
Your issue is with allowing automatic updates.
It is up to you to read reviews before any update takes place, as this is the only way to know if there are problems with updates.
Where did you get the update from?
Google will not provide older versions of apps.
Most other app stores will.
I can guide you in the way to return the app to a previous edition, or else you can use your browser to use social media until (maybe) the next update returns the function(s).
A browser is the recommended way to access any social media anyway.
