Just bought my wife an s7 today and ordered an s7 edge for myself. Her s7 will not download anything from the play store on home wifi. It works fine on LTE or an xfinity wifi hotspot. I have updated the phone to the latest software update. It works fine browsing the internet on Wi-Fi but wont download or update apps. The software version is G930VVRU2APB5 which was supposed to fix this issue if I'm right. Hopefully this issue can be resolved. I've already read up on others with this issue and have found no way to fix this besides going outside my house to use xfinity wifi. Won't work on my 2.4ghz or 5ghz Wi-Fi. I do not have a VPN service to try but that has worked for others with the same issue.
