If I'm on my linux box in chrome looking at an app on the google play web interface and click "install" and select my Nexus 5, 100% of the time I get a downloading notification on the Nexus 5 followed in a few seconds by a "error downloading app" popup. If I get on the Nexus 5 itself, search for the app in the play store and click on install it works perfectly.
Have I got some setting that makes this fail? Is it just generally busted? It is certainly no big deal, but it is irritating.
