ArcGIS - AGOL / Enterprise,
We tried overwriting a Feature Service after adding a new layer in the mxd from ArcGIS Enterprise and the New layer does not show up in AGOL Web Map used for Web AppBuilder or Operations Dashboard.
We are not adding or removing layers and overwriting services until this is resolved.
Logged esri support ticket referencing this bug reproducible at 10.4.1 and 10.6.
Did you have any special customization with your webmap before adding the new layer in the mxd such as the formatting of popups? I was working with ESRI to try to pinpoint what causes this disconnect between the mxd and webmap and we were unable to determine the root cause.
Our scenario showed up after just adding another existing layer from our geodatabase to the mxd for some context such as parcels.
Had to publish different (New) services and completely recreate the Ops Dashboard and Web AppBuilder Ops Dashboard theme apps to get the job done as requested.
Esri has now created Enhancement Request ENH-000108149 for these issues.
It is a roll-up of other bugs and enhancement requests that had been closed as "Expected Behavior" because users should plan ahead for all the layers needed on the initial publish of the service, creation of web maps and applications.
I hope I don't make any mistakes, forget anything, have any boss of me change their mind after that initial publishing step.
That perfect workflow scenario would seem to only work for a demonstration but even that would be frustrating if "something came up" while preparing the demo.
I'm looking forward to the fix for this ASAP.
This above link shows a thread I started with the current workaround, so at least you have an option not to rebuild your app, but it really seems like a hack job instead of the software seamlessly handling updates to mapservices when working with webmaps.
