Email notification on Watch does not vibrate like the rest of the notifications
I have my Apple Watch on silent mode (but vibrations turned on) and my iPhone on silent mode (from the side switch). Also on my phone I have turned off 'Vibrate on silent' and 'Vibrate on ring'. All my watch notifications are set to mirror my iPhone. All notifications on my phone have sound turned on (including Mail).
And now the issue: All notifications on my watch vibrate when they're received, except for Mail notifications.
But if I turn on 'Vibrate on silent' on my phone, Mail notifications will vibrate. The rest of the apps' notifications vibrate either way.
Does anyone else experience this or is it just me?
