I also quit social media . I did not have this experience. I had no problem following what went on with friends and acquaintances?! I don't know why you had this experience. I'm sorry you felt like that. but for me the info that is important always gets to me. And I enjoy emailing and using the phone and meeting people for social events in stead. And when I miss some post on face I always hear it from someone else....
It’s a matter of perspective and trade offs. If you are a person who experiences anxiety from missing things (FOMO) you are much more likely to notice this. I know since deleting my social media accounts I have missed out on a lot, only because my wife keeps up with stuff, but I cannot say how much I have missed because I really don’t care.
The other side to this is how aggressively a person is willing to take deliberate action to maintain personal relationships in the absence of social media automation. If you are that social butterfly who really owns that aspect of life you are likely to never miss any aspect of social media. Most people aren’t that good at taking dedicated action regularly reach out to people outside their most immediate circle though.
