My Legato application... disappears !

Just to share with all (share experience is the best !).
If you have a Legato application which disappears… It could be due to the “recovery” feature.
The recovery feature is reestablishing the previous “Legato system” (apps+framework) in case of fault of the last “Legato system” installed within the last 30 minutes.
This feature has been deployed on 16.01 in order to make safe the units deployed on the field in commercial applications.
Since 16.04, this feature includes also the ability to “force the Legato system as good” (–mark-good) to ease developer use case.
