[2022] Can't play ranked, despite connecting my phone number

I recently got back into Rainbow Six Siege only to find out that you need to link a phone number to your account in order to play ranked. I followed the instructions and set up phone authentication, but I still cannot play ranked. I am level 70, high enough to play in ranked, and also have Verizon, a supposedly supported provider compared to T-Mobile which does not have phone compatibility with Rainbow. Is there a step I missed? I waited a few hours at this point, have restarted my game and PC, but nothing seemed to be working. Some help would be much appreciated
