I have just updated to version 91.1.2. If I add an attachment to an email and send it immediately, it seems to work OK. If I try to close and save the email or if I wait before sending it, I receive an error message that says I don't have authorisation and the attachment cannot be sent or saved with the email. Also since updating I have lost the "Send to mail recipient" short-cut in Windows 10. All rather irritating.
