Hello, I am missing ListView in all applications. When using BluetoothLE add-on. I do standard operations, even started the project again - nothing helped. Maybe someone has encountered this problem? And if I'm the not only one with this problem, I put my applications on other phones - the same thing! Yesterday it was still working, today it's not.
