Optimization not being automatically generated for proper levels for complex dataset, resulting in generalized data being displayed at zoomed-in scale levels, rendering data functionally unusable.

Workaround

Define the geometry manually using Update Layer Definition.

Step 1: Disable Optimization:

1. Go to the Rest Endpoint of the Service as the data owner or an administrator of the organization.
2. Follow the procedure of this article (https://support.esri.com/en-us/knowledge-base/how-to-access-the-rest-and-admin-endpoints-of-an-arcgis-000027990) to access the admin endpoint for the service.
3. Click the sub-layer that's optimized.
4. Click Update Definition at the bottom.
5. Ensure the top of the page states 'Update Layer Definition', not 'Update Service Definition'. If it states Service, step 3 is likely missed.
6. Remove everything from the Update Definition JSON box and only add the following JSON to disable Optimization:
   1. {"multiScaleGeometryInfo":null}.
7. Be sure Async is set to True.
8. Click Update Definition.

Step 2: Re-Enable Optimization with all levels:

1. Go to the Rest Endpoint of the Service as the data owner or an administrator of the organization.
2. Follow the procedure of this article (https://support.esri.com/en-us/knowledge-base/how-to-access-the-rest-and-admin-endpoints-of-an-arcgis-000027990) to access the admin endpoint for the service.
3. Click the sub-layer that's optimized.
4. Click Update Definition at the bottom.
5. Ensure the top of the page states 'Update Layer Definition', not 'Update Service Definition'. If it states Service, step 3 is likely missed.
6. Remove everything from the Update Definition JSON box and only add the following JSON to re-enable Optimization with your own defined layers:
   1. {"multiscaleGeometryInfo" :{"levels" : [1,3,5,7,9,11]}}.
7. Be sure Async is set to True.
8. Click Update Definition.

Note: This may take a while, but once it's done, the geometry can be drawn properly.
