Don’t use FB, or any other social media, for that matter, to get your news or try to otherwise engage people in political matters...you will be miserable. I use it to keep track of kids and grandchildren, but gave it up for Lent and haven’t missed it one bit. I use phone calls, video chat, text message and actual visits in person (though mostly on hold for COVID 19) and I’m much more calm.
What a concept. Does that still work? Just kidding. People need to do more of that, particularly young ones.
Most mobile APP development requires Facebook for avatars, FacebookID etc... sucks.
