Using the android or iphone Wyze app, go to the ACTIVITY screen - you will see the number of steps for the day. Now drill down to the activity chart screen by pressing the anywhere on the activity screen. The steps on the first screen never agree with the bar chart value for the day.
As long as you see a success sync, before you check the App, the data will match
Both screenshots I included in the bug report were taking after the sync takes place. In fact during the sync the screen is locked out and the app cannot do anything other than finish the sync or fail. This occurs both in the Android and iPhone applications.
