Our geology students have been using collector gathering data points during their field camp. For the week of June 13-17 the app worked fine and all datapoints uploaded during the sync. For the week June 20 to 24 the additional new data shows on the phone
The phone is a Samsung. First weeks data included about 100 data points with some description information including strike and dip values. The second week which doesn't want to sync up includes an additional 75 data points.
