With Candy Crush Saga, Candy crush Soda and myVegas - every time I try to open one of the apps the following message displays: "Internal Service Failure. An internal error occurred. This can be caused by lack of network connectivity. Please make sure you have a good network connection." Then, after I click OK, another box briefly displays but quickly disappears before I can really read it. Then I am back at my phone home page. These apps did not all stop at the same time. They stopped working a few days apart.
I play on my phone (Galaxy S5). I'm at home so have a strong wi-fi connection in addition to full 4G bars. I've tried restarting phone, moving the data from SD card to internal storage, checked for updates. Nothing has helped.
