new user confirmation email/password email not working properly

Hi

So i recently had an issue with the site not sending any emails which i have now fixed using sendgrid and wp mail smtp plugin.

Now when i sign up as a new user, the confirmation email is received and this is what it says:
Username: testinggggg To set your password, visit the following address: https://www.perthtrueblues.co.uk/wp-login.php

so, as you can see, it’s only going to the login page. how do users set their password?!

when i click ‘lost password’ this is the email received:
Someone has requested a password reset for the following account: Site Name: PTB Username: testinggggg If this was a mistake, just ignore this email and nothing will happen. To reset your password, visit the following address:

no address is given!

what have i done?! also asked on WP support and sendgrid support.
