To each their own. I get the need to have historical chat and all, and I run a Mattermost server for friends for the last few years and I depend on history there too. But on Signal it’s really just what I use with work peeps for after hours non-Teams IT chat in case something breaks and they needs emergency help since we all basically mute notifications for Teams after work.

Correct, it will only have all future messages. Nothing historic. But it should sync literally everything going forward.

I use it on mobile and desktop regularly without sync issues. Has it always had that problem for you? I generally always get messages at the exact same time without fail.
