Today I noticed under "configuration" - "information" - "problems detected:" - "no internet access", both when using wifi and while on my AT&T LTE. I love the app. Just noticed it quit working for me today.
I use the 'CKPool Status' app on my Android Powered Galaxy phone.
The app has been working rock solid for me since I installed it over 2 weeks ago.
As of this writing it is still working fine.
