I am using the hosted version of Confluence and in the Calendars section, when I click to Add Calendar, then Add Existing Calendar, then search for calendars, I can not get any results from the search. I am able to find other users calendars if I share them via link, and after at least one user subscribes the calendars show in the Popular Team Calendars list but still are not shown in search results. I have tried with calendars in different spaces, with and without read/edit restrictions but none of them show in the search. I am not sure where to look to try and resolve this.
