Internet connectivity issue

I have mcoc installed on my phone and my tab (galaxy s6 lite). No problems on phone. A few days ago, I started getting the red flashing internet icon after a few minutes playing. Would restart the app, same issue. Uninstalled, reinstalled, updated, cleared cache/data, made more space on the device. Same problem. And this was before the most recent update. Any ideas at all why this started happening? As I mentioned, I play on my phone np so it's not my internet...
