We are sorry you're facing this issue. We know how frustrating that can be, however there is a possible answer.
If you've signed up using an identity provider like Apple, Facebook, or Google, there's no password attached to your account; that might be the reason why you didn’t receive any password reset link.You can try to log in with other identity provider's account by choosing the corresponding button (Google, Facebook, Apple).
Thanks again for learning with Mimo, and happy coding!
