Hello.

I just signed up for a TMDB account. Not a good first impression, as the verification email never arrived to my Gmail, despite several tries. The email was not in the spam folder either. It never arrived.

It worked on the first try on Protonmail though, so you you might want to look into why Gmail accounts are having issues with this. I've Googled several threads about this issue, with a TMDB support person saying it got fixed, but that was 10 months ago... So in other words, it's still not fixed.
