The worst part is it barely works. I’ll get more unable to deliver over RCS than I’ve ever seen on Signal, Telegram and WhatsApp.
Maybe for you. I’ve never had it not work, with the exception of Airplane mode, but that’s by design.
As soon I switch back to SMS it delivers straight away. The fact it doesn’t switch automatically further frustrates me because it’ll leave messages hanging, when you expect the text messaging app to send texts.
There’s a setting under Message’s RCS chat to auto resend as SMS if RCS can’t send. Have you tried enabling that? I personally haven’t because I also use RCS for E2EE for those who don’t use Signal. And I’d be irritated if my E2EE app sent it in plain-text/SMS without my explicit consent, which you’re implying you want (but can enable with that setting, which would be a blanket consent).
