BingAds API : Unable to update adgroup product partition

Question

Hello,

I'm working on a tool which helps our customers to create and manage Bing Smart Shopping campaigns.

I'm able to create a campaign with a given product partition on my adgroup, but I'm unable to update the product partition (if I want to exclude more brands for instance)

According to the documentation, the way to update product partition is to remove the existing tree and replace with the new one.

If I try to delete the previous tree and recreate it, I get an error at delete step. I tried with both criterion ids, and just the root one and get always the same error : The ad group criterion ID is not valid, althought whe criterions ID were previously fetched from the api.

I also tried to update & replace via a single ApplyProductPartitionActionsRequest, as it seems to be possible in the doc (For a Delete action you only need to specify the Id and AdGroupId in the AdGroupCriterion.)

Any ideas ?

Thanks for your help
