Evolution fails to connect to my Google calendar

I've configured 2-Step Verification with my Google accont (under https://myaccount.google.com/security) . Emails with OAuth 2 seem to come through fine but I keep getting "Failed to connect calendar “my.mail@gmail.com : MyName” Data source “MyName” does not support OAuth 2.0 authentication and Failed to connect address book “my.mail@gmail.com : Contacts” why is this and how can I fix that? I'm using Evolution 3.34.1
