We cannot sync my subgroup's calendar to external software via the iCalendar link. We can sync to the main group to devices such as iPhone, Mac calendar and Andriod's calendar. This requires no login credentials, just the link. When I try to sync to the subgroup's ICS link on iPhone or Mac, it fails (have not tried the subgroup with Google/Andriod).? If it matters, both groups have restricted membership, but the subgroup is not visible to the parent group.
Is there a way to make this work? I tried entering my username and password but that fails as well.
Thanks for any help.
