I've tried off and on to actually use Matrix. I was a bit of a loud supporter in the early days. Unfortunately, it looks like it still hasn't grown past the fundamental issues I was having then. It might be time to try something else
When I started using Matrix, Riot.im did not get notifications in time, or was a battery hog. And Synapse took up a lot of memory, with occasional slowdowns. But then, circa 2022, Synapse improved and Element seems to have worked well and was consistent and reliable on all platforms.
That's exactly the sorts of issues I was having. That and it somehow kept losing my encryption information so I'd lose access to all of my messages or something similarly ridiculous
