LinkedIn Login Nightmare! Help Me Recover My Account!

Hey everyone, I'm having a major problem logging into my LinkedIn account, and I'm hoping someone has experienced something similar.  I deleted the LinkedIn app from my phone to free up space and reinstalled it. Now, when I try to log in, it requires me to approve the login via an in-app notification – two-factor authentication (2FA). 

The issue is that this is the only device I use. I don't have a secondary trusted device, and I'm not receiving any notifications. I tried the "I don’t have access to this device" option, and they asked for identity verification. I provided everything: a copy of my national ID and completed the selfie verification process (front, left, and right).  Despite this, the process failed, and I still can't access my account.  The email associated with the account is still receiving LinkedIn messages, so the email itself is working correctly. 

Has anyone faced a similar situation? Or does anyone know how I can resolve this and regain access to my account?  This is incredibly frustrating, especially given how crucial LinkedIn is for professional networking in today's job market.  Many people are reporting similar issues lately with various apps implementing stricter security measures, so I'm hoping there's a solution.  Any advice would be greatly appreciated!
