Yes, it happened to me in May last year. I was referred to the adult autism team in my NHS trust and, honestly, I got a bad feeling from the outset. They sent me some short forms to fill out and when I asked about them, the psychologist told me that he had made up the screening questionnaire himself... TWENTY YEARS previously and hadn't needed to make any changes to it. The questions were very leading and blatantly based on ancient research that focused on the presentation in young boys.
When I turned up for my (virtual) assessment, he actually said "So many people are referred to me and I diagnose fewer than 20% of them. I also don't believe in this whole women-present-differently-to-men nonsense - you're either autistic or you're not. I doubt we'll be making a diagnosis today but you've been referred so let's get this over with" 
I'll admit that I was masking because I was anxious but he didn't dig any deeper and literally told me that I'm not autistic because I made a joke. Yes... I do that sometimes. There are autistic comedians! I make jokes, but I can't tell when someone else is joking. I felt incredibly low, like maybe I am NT but just a broken, rubbish version of it.
I left it for six months, then I requested the report he sent to my GP and I found my rage. I asked for a second opinion and the NHS team said no due to being short staffed.
Neurodiversity in women is my special interest so I used it to find myself a female psychiatrist who understands how autism presents in women and is up to date on current research. She had me do the AQ50 - I scored 47. She then sent me the most comprehensive, thorough screening forms you can imagine; it took me a week to fill out and there was another the same length for family members and my DH to complete. She asked for a full history of other diagnoses I've had over the years, family medical history, etc then we met virtually. She diagnosed me with ASD without hesitation.
I also have ADHD, dyslexia and dyspraxia, all diagnosed late last year at the age of 31. And diagnosed by different people (ADHD through the NHS; dyslexia through my university; dyspraxia by a private occupational therapist), so I trust that I really do have all of those!
