one quick question - is there a difference in the APIs between the DXP and the CE versions? I’m asking as we also have a test environment on CE, whose API doesn’t take into consideration the filter - e.g.:
There should be no difference in API as long as the versions are the same.
That said, if you are a DXP client, you qualify to receive non-production licenses that you should be using in your test environment, and developer licenses for local developer testing.
You should never be using CE when you are a DXP client. They have slightly different feature sets, they have different release cadences, DXP will get fixes that CE does not, …
Using CE is your mistake, not whether the filters are working or not.
