Canvas iOS App Calendar Question

[WCruse]

Hi! Our school is new to using Canvas--so far we're loving it--and I just got the mobile app for iOS but am noticing an issue with my calendars. The mobile app shows all of my calendars that are course-connected. However, on mobile, one of my calendars (listed under 'other calendars' on the web version), does not show up at all underneath the calendars section on mobile, with no option to select it anywhere on the calendar page. Any ideas or do other calendars that are not itself a course not show up there? (Even though they do on the web?)

Any help is much appreciated!
