The 'implemented' suggestion here does not do the same thing at all.
This is key functionality for us. We have a custom base map with set scales which our team need to see and print from, however once in Experience Builder the zoom scales do not persist, and are random. Either the option to set the zoom scales is needed, as per the original suggestion, or Experience Builder needs to respect the scales of the base map. We are using Experience Builder Developer Edition, so it is hoped there is a way we can force map scales in the back end?
