Progressive Web Apps - onpulltorefresh acton/event

Has anyone had any success with the onpulltorefresh in a PWA.  It looks like it isn't triggered based on our simple app build.

Just got the 11.9 update in a Personal Environment and still not seeing the onpulltorefresh being triggered.


please check this example from the forge.



What is behind using a custom component rather than the out of the box events? are we acknowledging that teh out of the box doesn't work?


Have had confirmation from OutSystems support that the inbuilt pulltorefresh for PWA's only works in browsers it doesn't work when the PWA is installed on the mobile device.  Does anyone have a work around for this, or are people just sticking a refresh button on the page?
