Using New Outlook on Windows for personal email, calendar, and contact management
Something has changed for me too. In Calendar> Interesting Calendars, my Outlook mobile shows a message 'It looks like there is some connectivity issue. REFRESH'. When you try to refresh, same message appears.
The sports calendars still show as checked if I select the calendar icon at top left of the primary calendar screen, but still no entries at all.
On my laptop, my Outlook (Classic, New & 365) show Sports calendars as checked, but Add Calendar is empty for Sports.
I agree that they have pulled the plug, hopefully to work on it. It obviously wasn't tested fully and disappeared in a release between May and August. I did have a problem with Birthdays and Repeat Events (e.g. Insurance renewals) disappearing a while ago, which I think is linked.
I agree with the Windows Phone comment/observation.
Kind Regards, PK.
