Can't access private calendar

We created a private calendar for the stake president (me), and the executive secretary, but it won't let me access it. When I subscribe to it, it looks like it takes, but then when I return to subscriptions it is unsubscribed again... Very frustrating.

We have seen this occurring with private calendars and have been working on identifying why this happens for a few days now. Just to verify, subscribing to non-private calendars works successfully?

Yes, subscribing to non-private calendars works successfully.

Ditto on this problem. I'm wanting access (with Ward Executive Secretary permissions) to the default Bishopric interviews calendars that were suggested and created at Initial Setup. The same issue occurs where in the subscription management window, the private calendars appear to subscribe--and hold onto their subscribed state as I switch between stake and ward calendars, as well as switching between other settings menus--yet when I switch to the calendar view, they lose their subscribed state.
