Instability with Schlage Z-wave

Is anyone else seeing instability with Schlage Z-wave FE595CAM716ACC

We are seeing these locks go online and offline every 30 minutes.

These ran solid for 5+ years. (3 years on the old drivers, 2 years now on the edge drivers).

We have 50+ of them, with the latest hub update they are constantly going offline at all locations.

We have tested with these Edge Drivers.
