I can't figure out when and how universal (or Android/Apple for that matter) “sees” there is a new version of the universal GUI installed on the webserver.

I tried several things and sometimes I got it to work, but no clue when and how the message “a new version is available” is shown after logging on the the universal app. Changing 

Changed installNotificationExpirationInDays to various numbers.

My settings in config.json


  "defaultApplication": "something_portal",
  "defaultPlatform": 3,
  "loginOptionsDisabled": true,
  "loginOptionsHidden": true,
  "installNotificationDisabled": false,
  "installNotificationExpirationInDays": 20,
  "useFormFieldBackgroundColor": true,
  "serviceUrl": "*****/iam/iam"


Anybody an idea how to “force” the installation on the device?

Hi Henri,

In this topic we explained more about the Install on PWA's: 

The "A new version is available” I believe should trigger if the Universal GUI was indeed replaced on the webserver, and/or the user tries to interact with the application.

Forcing an installation is not possible to my knowledge, the user will always have to press the install button.
