Hey @NicholasTota1
I found this post here mentioning similar, it appears that it could be related to email verification or possibly a community manager may need to verify your account manually if there was any bugs:

Refer to the comment made by Jesse Cloutier here. I would also try to log out and log back in to try once more, maybe it's a caching issue?
If it is the case that it's a bug and you need manual approval, I would send a mail to Jesse Cloutier to request manual verification: https://community.esri.com/t5/notes/privatenotespage
