Hi team

Hoping you can help (and be patient with) a "Learning Geek", as numerous Google searches have not been useful thus far.

I have two Android phones - an S8 and an Xcover.

I have an @gmail.com calendar. 

I can see all my calendar entries on the S8 - but I cannot seem to get these calendar entries to transfer/sync to the Xcover.

The S8 is using the Samsung Calendar (I think it's also called S-Planner) app. The Xcover is using the Google Calendar app. Both appear to be signed in to the @gmail account.

On the S8, all my calendar entries corresponds to the @gmail account listed under Google in the Manage Calendars section. There is also an @gmail account listed under Samsung Account but entries are not made under this calendar.

When I log into Google Calendars on a browser, none of the calendar entries I've made on the S8 show up, even though it's on the same @gmail account.

What am I doing wrong? Any ideas on what I've missed?

Thanks!
