Adding Google calendar after email add

Question

I find this particularly annoying...
I had to reset my phone and on adding back the accounts added my gmail account, then spent hours hunting around for the option to add the calendar without success. I remembered I had done this previously without problem but forgot how I had done it.
Then in desperation I deleted the account and added gmail the automatic way (i.e. just typing in the email address from the first screen) and low and behold the calendar options appeared.
Why isn't the option there when you add manually (unless in the 2 hours I spent, I missed the obvious)???

Answer 1

when you use the easy configuration, the Z10 will understand that one account stands for three (email + contacts + calendar) with the same credentials, but three different servers.
when you use the Advanced configuration system, you have to specify explicitly the URL for each server.
So if you want to add a specific calendar from a GMail account, you must fetch the exact URL of that calendar (in the options of the Google Calendar web interface) and input that on your Z10.
This is very useful for example for people who have several calendars on their GMail account.
