Why can't I install any apps from the google play store?

Upgraded from S5 and used Smart Switch. No apps came over during the transfer. No problem, I'll reinstall them, right? Well, I was able to install a few - Facebook, Twitter - but after that things just hang on 'downloading' . What is wrong with this phone? Thinking of taking it back and just keeping my S5...

Hmmm. Turning off my wi-fi seemed to work. But who wants to use all of their data to re-install apps?

The correct answer is similar to this

Basically you have to go into your router's settings and disable IPv6. The Google Play works fine over wi-fi after this.
