Hello, could you try to use the option businessAttributeUpdateBehavior=replace on your POST requests to update managed attributes? Recently Purview team advised to me to do the steps I share below, and it worked. Sharing with you and hope it will work for you too.

Steps:

1. Create your managed attribute in Purview if you have not already: Microsoft Purview -> Data map -> Managed Attributes -> create attribute group (YOUR_ATTRIBUTE_GROUP_NAME) and specify an attribute under the group (YOUR_ATTRIBUTE_NAME)
2. Example of an entity POST request should look like: https://{{YOUR_PURVIEW_ACCOUNT_NAME}}.catalog.purview.azure.com/api/atlas/v2/entity?businessAttributeUpdateBehavior=replace
3. Body will have to contain the section for managed attributes. Basic skeleton:

{
       "entity": {
        "typeName": "ENTITY_TYPE",
        "attributes": { ... },
        "guid": "ENTITY_GUID",
        "relationshipAttributes": { ... },
        "businessAttributes": {
            "YOUR_ATTRIBUTE_GROUP_NAME": {
                "YOUR_ATTRIBUTE_NAME": "VALUE_YOU_D_LIKE_TO_ASSIGN"
            }
        },
        "displayText": "ENTITY_DISPLAY_TEXT"
    }
}
