I have a Google Pixel 2 and I would like to add an external calendar to my Google Calendar.
If I use my computer, I can login into my Google account (the same account I'm logged in with my phone), go to the apps and open the Google Calendar. Once there, I can add a new calendar by providing a URL, and automatically the new events of that calendar are added to Google Calendar.
I was expecting to see those events in the Google Calendar of my Pixel 2, but they don't appear. What am I doing wrong?
