Louis, trying to debug location in G+. You've got latitude switched on and showing you're in France but your G+ profile doesn't show this. Deliberate?
Also wondering if you have a Chromebook with you. Is the location experience in G+ on a Chromebook just like using Chrome on a laptop?
ps. apologies for taking your time. Just ignore me if you're busy!
The Chrome experience on the laptop is very similar to ChromeOS. The Pixel has the touchscreen, of course, and tight integration with Drive for local docs, etc. I really like mine. It's all I use.
