For some reason Connect IQ Android app doesn't allow me to choose "date" with the "date picker". Choosing the date works in emulator. I am using the latest SDK (7.2.1) and Connect IQ app (2.29.1)
In short, when I go to the data field (Tminus by me) settings in Connect IQ app and try to choose a new date it simply highlights the wanted date, but doesn't change the field value. In the emulator (Edit persistent storage/Application properties) it works as expected. Hence I don't know where to find the issue.
