Facebook disabled me because of an Instagram account I barely use

Facebook disabled me because of an Instagram account I barely useGot a notice saying my Facebook was suspended because it’s linked to an Instagram account that supposedly violated community standards. The strange part is my Instagram is still completely fine and active, I can log into it right now with no issues. It’s just the Facebook side that’s gone. Filed an appeal explaining the disconnect but haven’t heard anything back yet. Lost access to years of old posts and messages with family overseas, which is honestly the part that stings the most. Anyone know if the two review processes are actually separate, or if fixing one side would eventually fix the other?
