Apologies if this has already been posted/solved already!
My organisation has recently started creating apps using experience builder in AGOL, rather than WAB.
In the past, we would have dev, test, and prod versions of WAB apps and apply changes to each by copying json across using AGO/ArcGIS Assistant (and repointing web map/feature service URLs etc). This worked well and we could see the changes when editing the prod version of the WAB app.
This does not seem to work for experience builder apps though, as changes made by copying json do not show up in the edit interface, but do when accessing the app directly.
I've added three screenshots that show this below (all after json has been copied).
Any help with this is much appreciated! Being able to make quick changes/bug fixes for the prod version via the normal edit view is very useful and would be great if it can be fixed.
Using https://assistant.esri-ps.com/ instead of https://ago-assistant.esri.com/ solved this problem for me!
