You have better luck than me.
Well, I’m quite stubborn and I bombard support teams with emails. I’m not sure if that makes me lucky 
My guess here is that Google maps is not free when integrated into an App and THS has removed it to reduce costs.
Now, if that is the case this is quite ironic.
Increased membership and introduction of booking fees for sittings, one reason for those was the improvement of the App… I wonder now where the money goes…
I really hope to be wrong.
