I had a nice one today. I saved an email for archiving for all to see ( you know, as a .msg) and tried to open it. Windows asked if I would like to open it with Outlook (new). Sure, I thought, only to be greeted by the message "sorry, this function is not supported".
Why do you do this to me Microsoft?! Why?!
So why not use something like WhatsApp or Signal instead then? Sounds like a terrible user experience to me. Nobody I know uses iMessage, everybody uses WhatsApp instead, which is platform agnostic.
But I'm European, so the iPhone penetration is lower iirc and they can't stay in their bubble as much.
