The MT status page shows issues with problems and/or maintenance on all platforms except voicemail.
I noticed early today that some expected emails had not arrived, and the MT site confirms that MT's email service provider is carrying out maintenance until 2nd June to improve reliability. In the meantime I can log on to email via webmail and see messages in my inbox, however these messages do not show in the inbox on either my Mac OS or iOS apps?
I guess that MT telephone support is now closed until Tuesday, does anyone have any idea how I can get the emails on their IMAP server to be synced to my devices as normal?
