FYI: Version 27.13 update removed all Connect IQ apps

Here all was fine as well. Looks like for some reason your device experienced a full reset.

it was not a full reset, all other settings are ok

How did you update?
Did you use Garmin Express?
This is notorious for *** Connect IQ apps/widgets up.
Since years it will delete apps wich you installed with your phone and re-install some that you deleted with the phone.

It seems that it doesn’t really look what is on the device but rather look what should be according to its own memory. 

Nekem teljesen letörölt mindent! Újra kellett kezdeni az egészet!!!!

The Update was made by android phone with Garmin Connect and Bluetooth 

Updated direct from device via wifi

Updated today, it removed the mapdashboard app, but left the tempe app weirdly 

My MapDashboardMS data field settings were lost during this update. But the data field was still on its place on the data screen.
