Cat weight not updating on the tracker?

Hi all, we got a PetKit (Max with the camera on the side) and our cats are finally getting used to it. I added their weight to their profile after they first got in, and there's a scales icon on the app that suggests that it should update their weight every day to keep track, but since I entered the info on Thursday it's still saying "last update: Manual". Is there a setting I need to do to sync the weight? appriciate it won't be 100% accurate but it'll still help track if it goes up or down

Thanks
