Previous versions had the option to select different vibration patterns, which was a critical feature to distinguish from other app notifications. Please bring this option back in the latest version.
Indeed! That sucks. LED notification was removed, too.
Also, switch off vibration should be allowed. I want to be notified about incoming emails in the notification section above but I do not want be disturbed with vibration for every singel email.
Turning off vibrations is already possible using the Android notification settings (even per account)
