Status of returning M values in Map Viewer?

Where are we at in Q2 2025 in terms of obtaining the M value (or finding a location at a specific M value) in the default Map Viewer and/or ESRI apps? I'm not talking about routing- I just want to find "milepost 3" along a route or click a location to have it tell me that it is Milepost 3.

In desktop Arcmap, there's always been the Identify Route Location Tool and Pro finally incorporated this functionality into the standard identify function (Explore Tool). In more recent years, this task could only be accomplished if you were using the Roads & Highways Server Extension but I swear I had heard/read that this would be finally coming to the standard Map Viewer or Apps (possibly as widget functionality in Experience Builder) but I just can't find that.

Hi @SteveCole

Yes, support for working with M values in Map Viewer is on our future road map, but it is not for Q2 2025. Thanks for providing us with your use case for working with them. When we add support for working with M values, we plan to include support for entering or editing M values. Are you saying that editing M values is a lower priority for you than viewing them?

Yes, I am not at all concerned with editing M values in a web map. I simply want to locate a specified milepost (or river mile etc) or click to learn what the M value is where I clicked. No editing whatsoever.
