IMMI Go lower anchor strap tightening 

Thanks for the video, it was helpful but I still struggle because I have zero space to do it, my hands don’t fit in the tiny space to do it how do you lose the strap of the booster car seat? Thanks 🙏🏻 PS: I am a babysitter who has not much experience with it

I’d love to know how to now LOOSEN this. I’m tasked with taking booster seat out of a car and I cannot.
