An odd thing has happened to me with Google Calendar.
I started with Google.com on my desktop pc.
Then selected Google Calendar.
I made entries.
I go to my laptop and to my table, open Google,
and select Calendar and all my entries are there.
Good. So far!!
Google Play (or is it Google Store) has an app called Google Calendar.
I install it and look for my entries.
Nothing. No entries.
There seems to be 2 Google Calendars
and they don't talk to each other.
