OK +Google or +Vic Gundotra what did your team do to Hangouts?
I have a iPhone 5s and a Nexus 5, and ever since the iOS Hangouts update the Android version has been on the fritz.
If someone sends me a message before the iOS update, both devices will get a notification simultaneously. Now the iPhone gets a notification, and it never gets sent to my Nexus 5, in some cases the message never even appears. I had to literally log out of the app and log in to get it working again last night, and today it started again.
Extremely annoying. Please fix soon.
