A lot of professionals, highly educated people in the psych community, either don't believe DID even exists or maintain an absurdly narrow view. Most of those people have either never known or worked with someone who had it or base all their knowledge on the handful of cases they've witnessed first hand or research they can bring themselves to agree with.

I went in to treatment over a year ago with a depressive episode and CPSTD symptoms, was apparently screened for DID and didn't 'pass the test'. I talked about it with my T later on and she said she was the one who screened me.

I've since looked up the DSM online and have no recollection of ever being asked those questions and can only guess that whoever was 'out' during that appointment (I was beyond freaking out, I realize now I was switching all over the place at the time) either wasn't aware of it or didn't want to talk about it.

It seems as if in order for DID to be obvious or diagnosed quickly, one has to be drastically triggered and switching constantly in dramatic ways, which isn't how it is in a lot of us. It takes time for other people to see it and if someone doesn't want to, they probably won't.
