Hi.
I started to test your App on a Hangout with my friends. At a given moment I changed to Google Effects to show myself with a Pirate Hat. When I changed back, I tried to activate your App, then my custom overlay was on the upper left corner of the screen!
I thought "ok, next hangout it will be on the right place". But it wasn't. Now, every time I activate the Lower Third my name and custom overlays are placed on the upper corner.
It's just with me or I'm just lucky?
