App load/ready event not triggering action

Wappler Version : 3.9.7
Operating System : WIN10
Server Model: NodeJS
Database Type: Postgres
Hosting Type: Docker

To a page’s App element I set a Dynamic Event to trigger an action on App->Ready event.
I tried several actions, like scrolling to a specific part of the page, but also showing a notification.

None of these actions are triggered however, so it seems the event trigger is not working.
Also tried with App=>Load event, which also doesn’t trigger the action:

To be sure it’s not the actions that were setup incorrectly, I added a button to trigger the actions and they work well then, so it’s definitely the event that’s not fired or not triggering the actions.
