I do include 'Summary' paragraphs at the top that provide a TL;DR for an entire 1-ish page doc. I think people will usually open the doc for a few seconds maybe and then brush it off because the general team culture is that all important information will be passed verbally anyways so no point reading now.
Actually I guess I would like to encourage the entire team to do a bit more of this practice of writing things down. For instance, tickets are usually just ~3 word titles with no context or specifics. It's only once the team meets and verbally describes what the tickets mean, that the work can actually be done. I've noticed this sort of culture at multiple companies now actually.
As for the tickets, is it a problem that work isn't don't on them before the meeting?
But that's about how to push them. Have you asked them if the documents are hard to read? What are their length - are they overly long? Have you done any testing to see if they even open and struggle with the documentation before they call you?
