Did the iOS Hangouts Update, Break the Android Version?

Ok so you guys might be looking at the title like WTF? But 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, in some cases the message never even appears.

Is anyone else having this issue?
