Congrats on passing!
Seems there's a general issue with emails being received from ISC2 at the moment judging by all the people complaining about various emails not having been received.
The last endorsement I provided was last year prior to the "updates" to the member portal, and I'm struggling to remember it exactly...
Back then you'd be sent an email with a unique link to the endorsee's application, but I'm pretty sure the form was also accessible just by logging into your own profile - although that may have been after you initiated the process using the email link.
If it's going to be anywhere on the new portal, I would assume it would be under the same endorsement link you went through to make the application: https://apps.isc2.org/
Otherwise, it's time to call Member Services:
https://www.isc2.org/Contact-Us#accordion-ec0be5accd8a4a36a5dbbcd3adb5307b
My recommendation if you do need to speak to them is to call them and keep calling until you speak to someone as voicemails and emails will take a while to get a response.
