Hello - I am working on an experience builder where the client requested that viewers could not zoom at all. I have zoom turned off in the Map -> Content -> Tools section, the Map -> Content -> Options section, and made sure that zooming/panning are turned off in the map actions. The zoom is disabled on the web view, but not in the mobile view. I can still zoom and pan around the map when viewing on my phone. I looked at the code and the zoom function is definitely disabled, the mobile view just isn't honoring the setting. Let me know if anyone knows how to fix or workaround this issue.
I would suggest getting in touch with your local Esri Distributor and ask them to investigate this further for you - it may be a bug that needs raising
