I have on just about each & every device more then 2000 errors: ie

Number of errors not acknowledged: 2119

They are mostly rubbish like:

Could not add bundle 1a73654f11af259e27668e2c5a3e5f20 to session

which means absolutely nothing to me.


ZESService is not available for interaction: : IsAvailable() failed

which also is not clear at all what it means

Looking at the devices looks very scary, as mostly it is error after error
(while in practice they do actually work fine)
