@Patrice64 I'm not having any problem at all accessing my calendar. You might be having problems because:
1. You need to be in hosting mode to see your calendar (on the app you need to switch back and forth depending on what your are trying to do), or;
2. You have inadvertently created two profiles by using two different login methods, i.e. one using an email + password login and a social media log in. If this is the case, log in both ways if you can and see which one has your listing and calendar.
Hope this helps!
