Congrats! I wanted to chime in as I didn't see this response from anyone else. If using the tethers that snap into the metal anchors they generally need to be connected straight with little angle introduced by the tethers.
Should there be a load on the car seat, any angle from the tethers will amplify the load to the anchors. See the link below for a lil better explanation.
