We checked the app and all works fine.
When you reset the password you should follow this procedure:
1) Go to https://app.aire.link/lost-password and fill in your email
2) Check your mailbox for email with password reset link
3) Click the button in the email. It will open page where you need to enter new password twice.
4) If both passwords match and fulfil the minimum password complexity requirements it will automatically log you in.
Let me know if it works for you.
