Okay so, 1.1.7 hopefully address the double graph in Android. This is a problem with Android and the flot library as it has been reported for the flot library.
For the table view, the time is now shown (1.1.7) in seconds, minutes, hours, days (w/e is needed) so no rounding is done. Also, the app has always emailed exact second runs (no rounding or minutes).
In regard to your other issues, I honestly don’t get what is happening so if you can I would like to try and troubleshoot while you are on and experiencing the issue. I will send you a private message so we can coordinate such a time.
