AirVantage - Cannot install application over the air

Hello,

I tried to install an application to our Legato system. I build a legato from scratch (18.06), and I build a MangOH to it. After I installed the whole system to the board (with update and instsys commands), the board was able to connect to AirVantage and after the board sends up the application list I saw the so called redSensorsToCloud application with version number V2.0 as installed application on the AirVantage dashboard.

After this I modified the application (redSensorsToCloud), and I built a new version (battery handling has been added). I modified the .app file (I changed the version from 2.0 to 4.0 and added the new battery related keys).

I created the package with the legato builtin av-pack utility, that generated the manifest.app file and pack it together with the update package (I tried with zip and mksys/mkapp too). I could upload it without any error to AirVantage, but after the install hangs, with the next messages on client side:

Could you please help, what I made wrong?
Thanks!

Can you synchronize your module with Airvantage before using the app ?
