Home automation (ligh turning on upon arrival) working on one iPhone out of two

So I have set up my smart light, via Home Automations, that upon arrival "home" of any of us within specific times, it turns on (and turns off after 30 minutes). I set it up on my iPhone and shared to my GFs iPhone.

The problem is it works for her when she returns home, but not for me. Is there a specific setting on iPhone that I may not have turned on? I checked every location sharing permissions and from my point of view everything is allowed. I've tried to remove and set it up again, with no success. We both have latest iOS version.

Thanks
