TypeError: f7Instance.views.create is not a function

[Vue warn]: Error in mounted hook: “TypeError: f7Instance.views.create is not a function”

I’m going around in circles trying to work out what is causing this. Anyone come across it before?

Still running into this issue and it’s causing a stall on the splash screen. Any idea on how to hunt this down? Unfortunately not pointing to lines in my files.

I’ve tracked it down the calendar code used in the kitchen sink. Something in here: jsfiddle.net/njvan/m4f1dw8r/
