Sketches disappear – DISTO™ sketch Review

Basic functionality is good. Peering did work for IPad Pro and iPad (2012), IPhone 5s through barcode scan. iPad from 2011 crashes during barcode scan and Bluetooth peering didn't work. Moving the measurements to the lines you have to 'move' the number. Don't expect to select it and then move your finger. Worst thing, my sketches just disappeared for the second time. Used the device yesterday for the first time and when my measures were gone this morning I thought maybe my fault. But it just happened again. 10minutes ago they were in the app, looked again now and only 1 measure of the 100s I took is left! I just lost a days work AGAIN! Have to return my Disto and get a Bosch unless this gets fixed or someone explains to me why this happens.
