Location anchor objects drift around

Objects in a scene with a location anchor seem to drift around quite a bit from where you place them, even when you're just standing still looking at them

Altitude only seems to change give or take 10 cm or so, but horizontal plane position can drift around up to a couple of meters from where you set the object to be ... even when you're just standing still and not moving the phone ... i.e. they move around with a mind of their own while the scene is running

Hoping it's an app bug that's being worked on and not just a factor of GPS accuracy that will always be a problem
