I just received my WM100 yesterday and am having fun playing with it. Yesterday when I tried to review history the screen would show "Reading History Data" for a few seconds and then an error message advising that there was an exception and that the app would restart. I did this several times and could never see any history. Today I can read some of the history but when I scroll down a little I get the same exception message and the app restarts.
I am using a Moto X2 running Android 5.1
fyi - I think I received one of the last of the first batch of these units. I ordered it on Apr 6 and noticed that the following day they were out of stock.
