Komoot on fenix 7 solar

Hi, my Garmin fenix 7 is connected to my android phone.

When on komoot app on phone i send a route to my fenix, the fenix says 'route received' When I click on this on my fenix it says downloading, after 20 seconds it says 'cannot connect. open the Garmin connect app on your phone and try again'

Nothing works? 

I have paid for komoot but cannot get it to work on my fenix? Can anyone help please
