Ok so in general I'd chalk this up to being disinterested, but I think this is relevant for a product meant for people with ADHD:
After a couple pages of choices, I was met with a screen with options A through K, and I instantly closed the tab. I didn't even read what it was asking. I realised that this may literally be ADHD like behaviour, so I opened it back up again, but it was still quite overwhelming and it took conscious effort to read through the form. I think this is just because I'm used to just entering my email and password, or using social logins, so filling the form seemed to be a substantial point of friction (even though I realise how it could be useful)
I'm unsure if I have ADHD, and it's never been a problem for me, but I sure do have a short attention span haha
