My organization has just recently started using Calenders for Confluence but I've had a user come to me not being able to add calendars for them to watch. The calendars they are attempting to add to their watch list show up under "Popular calendars" but when I tried to go search for them and add them individually they wouldn't show up. The user and I tried adding them as a group from Popular Calendars, adding them one by one from Popular Calendars, and then searching for them individually at which point they didn't show up. Does this sound like a specific user issue or something else?
