I have a 2020 Volvo XC60 and I can’t seem to install our cybex Callisto behind the driver or passenger because of these little plastic bumps on the seatbelt that prevent the belt tensioner from shutting. I have to imagine such a popular car seat is compatible with my car because it’s such a classic family car?? Am I missing something? This was a problem with our Nuna Pipa as well but a local CPST was able to position it just right so it would close. I did bring it to the Volvo dealership to try to get help and they told me they can’t help with car seats because of liability but they’ve never heard of anyone having this problem.
