My child's Apple Watch location not updating on my iPhone

So I’ve tried everything but my child’s Apple Watch location is not updating on my phone. The Apple Watch location updates on my husbands phone and also my sons phone. So nothing wrong with location services on Apple Watch.. And on my iPhone I can detect location of husband and son and vice versa so nothing wrong on my end either.. There just seems to be some disconnect between my phone and the Apple Watch. Any suggestions?
