It's an interesting situation. I think that despite the issues, Meta is the best (and fastest-learning) platform for mass-market purchase conversions. Linkedin has powerful targeting options, but the fact that it's tied to GMT drives me nuts. For LI, typically I use manual bids so I can easily dial down delivery at off times (e.g. if the ad objective is booking a sales call).

All in all, these ad platforms are tremendously complex software systems, and as someone who has been a fulltime software engineer I have a lot of sympathy. But with so much money is on the line, the standards are high.
