LinkedIn Sends Login Code to Old Phone Number

I have been unable to access my LinkedIn account since last night. When I try to sign in, the system still shows my old phone number, and because the verification code is being sent to that old number, I cannot access my account. I am not receiving any verification code on my current phone number.

I have attempted to log in more than 10 times since last night, but the situation has not changed. I tried to find a solution through LinkedIn's help and support channels, but I could not find a support team that I could contact. Since my entire career history, connections, and professional network are associated with this account, being unable to access it is causing me significant inconvenience.

I request that LinkedIn restore access to my account, update my phone number, and allow all necessary verification steps to be completed using my current phone number.
