One Time Notification

Hi all! New seller here. Trying to set up my deposit info and when it sends the one time notification code to my phone it never arrives. I resend it and it never arrives. The phone number is correct in my account. Whenever I have the code sent when I’m trying to login elsewhere on Amazon it always gets delivered. I have tried this from 2 different phones, different browsers, and the seller app. Chat support just said to clear my cache on my browser, didn’t work. Any tips?
