Okay, now sometimes appointments added via Appointments+ show up on the Google Calendar. However, when they show up, they are 60 minutes long. My settings in A+ are for the appointments to be 90 minutes long.
Appointments are booked at http://irgwebsites.com/rifka/book-an-appointment/?app_service_location=54002200220096
I have granted WPMU Dashboard access to this website.
Why is this?
I also have another open thread at https://premium.wpmudev.org/forums/topic/i-have-a-client-with-the-following-needs-on-monday#post-802265 for some other issues with this plugin.
