the proper flow widget with glance view

I have widget with glance view and data is not loaded, flow (e.g.f6pro)

- app start

- glanceView collects data D

- enter full view

- app.onStop save D using setProperty

- app start again

- fullView.onShow tries to read data - null - XXXX

- fullView.collects data D

- BACK

- app.onStop save D using setProperty

- glanceView.onShow tries to read data and find it and shows data

Question: why in XXXX there is no data?

On sim everything is ok, but is dificult to emulate BACK (but this run well on device)
