As an addendum realize that these kids were making that awkward transition into pre and early teen years at the height of the COVID pandemic. Social media was a connection to their friends and peers that they did not see in most large social gatherings for at least 6 months if not closer to a year.

Now my kids have mostly transitioned into smaller group text chats and Facetime conference calls with their closest friends as they are getting older. They are also heavily involved in sports and other activities where they're invested in getting better versus the constant competition of social media.

I have also instituted an Apple-only devices in the house because while they do have their short comings, the Screen Time settings do work very well. I don't monitor my kids closely, but I do limit the amount of time they can spend on social media services, YouTube, etc.

edit: I'm Gen X and our major problems in middle and high school where alcohol and drugs and everyone smoked. I know multiple people that died due to drug overdoses, mainly heroin, in the early to mid 90s. I have friends in their 30s and 40s that developed lung, throat, or mouth cancers. Thankfully, at least locally, that's not a problem.
