I've had the same issues and a similar experience after using Signal the past few years. It took so much effort to convince my closest friends to install Signal and the single most frustrating thing it would do is force us back to SMS because sending of encrypted messages would continuously fail.
What really sucks is that there's no hope of me convincing them to switch again if a better messenger were to come along.
