[2022] Cannot queue ranked with squad due to MMR difference, but we are the same rank

My Uplay account username is 'The_Archanist' and my friend's username is 'Rigbonez.' and my r6 siege rank is Silver 2 and his r6 siege rank is silver 2 as well, but we cannot queue up for a ranked game in r6, because it says 'Squad MMR difference is too high', although we are the same rank. We tried restarting our game and uplay and even our pcs to queue up for ranked, but it still says the same thing. We tried to verify integrity of game files on steam as well and it still doesn't work. I've seen the same issue happen on another person on a support forum, and the issue was left unsolved. I think there is a problem with the servers or something, but this kind of client issues on rainbow six has happened for a long time since I started playing rainbow six back when it was operation health.
