We are getting this error in all our Mobile devices when we try to open Accounts view. We have changed nothing in the system, i suspect that this is due to the last update during this weekend. 

What happens is that the mobile device is trying to open the account view in "Calendar Control" instead of "Read Only Grid". When we change to "Read Only grid" it works fine. But how to change in the App that the default is "Read Only Grid"? and this only happens in the accounts entity, that of course nothing to show in Calendar View. 

Anyone else have this effect?
