Offline Area not supported if Webmap has duplicate layers

Question

I would like to enable the Offline Area to allow fieldworkers to work in remote areas. Unfortunately, the system doesn't allow me to enable it because of the way my Webmaps are set:

I have several layers that are duplicated because each copy has a different setting in terms of style, filters, pop-ups, forms, and labels. This is apparently not supported for Offline Area.
Other cases include a feature layer provided by my client (thus I don't own it) that has field names with more than 31 characters and other layers (specifically a Join View layer) provided by my client that don't have the sync enabled.
Are these going to be addressed for future releases? The Offline function would be a very useful tool for us since it often happens that our crews are in out-of-reach areas, so they are forced to collect the data with other tools and populate the forms when they are back in a reachable area.

Here are some screenshots of the issue on Field Map Designer

Thanks in advance for any help!

Regards,
Andrea

I agree that it would be convenient for layers that rely on the same source to be able to coexist in an offline map, but I have a feeling we are not going to see that anytime soon.

You would have to create a view for every layer that you have control over, then add those views to the map instead, so each layer/table in your map would be pointed to a different service.

Not sure about the Join View Layers, but as you are discussing in your other reply, I do have a feeling that a script will be required to move data between services.  The script could easily capture the layers that match, even if you have to truncate field names on your own end.

You could attempt to create a new layer from the join/view layer service as a template.  You may also wish to create your own service as a link to the existing service, but I have a feeling you won't be able to necessarily trick it to sync that way.  At some point, the editor fields and the globalid field are going to have to exist in your own service.

There are also ways to have collaborations where services can sync from one org to another, but that could be a security issue depending on your orgs (and I have only seen it function once, and I believe it had some hiccups - that was also on Enterprise and not AGOL.)

Where the data lives (AGOL or ArcGIS Enterprise) I am sure will also be important on whatever the final solution is here for you.

Hope this helps.

I can understand this from this point of view. It would be ideal if, by disabling the edit for each duplicate layer from the WebMap Designer, the Offline function would be available since only one copy for each layer would be editable.
Concerning the syncing, I may ask my client to enable it, but I don't know if Join View Layers have that option.
