Facebook has been notorious for just showing partial amounts of “friends“ stuff.
I purged my Facebook of many people , but some I checked there page and some for whatever reason there stuff wasn’t showing on my feed.
I often share things , cute animal pics or positive stuff and many times I get not a single like or whatever , I’m just fine with it now , use to bother me.
But my page is for me , I love just pulling up my page when I’m in a lousy mood and see all the great stuff I have posted.
