I have multiple dashboards and ExB apps setup with web maps. While I can still set the default extent via the web map, it no longer functions in the same way. The default extent seems to depend on the browser window size, but in an incorrect/illogical manner. I'm unable to get my apps to open at the extent I expect them to, or that they used to open at.
This all changed around the Feb 2024 update I believe.
Whether my browser window is maximised or not when I set the zoom level, should not affect the saved map extent. Currently it does. Previously it didn't.
