In one of the .mxds you are using the Maplex labeling engine. Try changing it to on/off to match the one that works

Would recommend hitting 'analzye' prior to publishing the service. Often picks up if there are any compatibility issues that may cause issue after publishing.

Please don't forget the kudos 🙂

Analyze does not identify the compatible issue !!!! Which it should.  Maybe is a bug need improvement.

ESRI never tell us that standard label engine will not compatible with arcgis online map viewer. You have to figure out on your own.

I have called esri customer service, they create a case with case number, however, they don't know what is wrong, don't know what to do, eventually they said they will escalate it to higher level team for further investigation.

I don't think there were direct compatibility issues. Sometimes what is configured in the desktop - e.g. fonts - aren't supported in the web service. The analysis button often picks them up and lets you know of the error or if it will be downgraded.

ArcGIS Pro is a much better experience sharing to the web. It's software designed for this. I would recommend you look to migrate to ArcGIS Pro.

Glad we were able to resolve it here.
