Is There a Problem With Messages Coming Online Offline?

I would be kind of curious about like what you can and cannot do. Like, for example, if I want to know if somebody said the message, that would be a tricky bit where I think I'd want to get that. There's this free PDF, free, free book for me that can find that online stuff goes bird or like an anger, we can link it in the show notes. And there's also like an chapter on exactly this, like, at some point, you might get in a situation where you have to shed load. It's not fun. At least brain wise.
