Both my son and daughter run these brakes.
I’ve not had major issues so maybe this is too obvious / something you’ve tried but when I changed the tyres on my son’s bike and when my daughter’s was first delivered there was a small amount of rub. I just released the qr and adjusted things that way, moving the wheel fractionally one way or the other and all was fine after that. This has been on a front wheel and rear wheel respectively.
This might be too obvious, as I mentioned, but hope you get it sorted. They’ve been decent enough brakes for basic cable ones imho.
