Hi, I’m now using outlook, if i could delete Apple mail I would. Outlook allows you to send jpgs as attachments as long as you start from the jpg, if you start from a new email it will embed them.
Knowing Apples modus operandi there will be some paying service (probably involving the cloud) coming up which will miraculously mean you can attach jpgs and screenshots as before.
You may also have noticed if you forward emails from mail which had attachments, they will not forward the attachments, in some cases it is not possible to forward the email at all.
I’m accelerating my move to Microsoft and android as this behaviour is disgusting. Apple hardware is for the toy market, they are not capable of being reliable business tools. I hope many more will follow suit.
