Same console priority?

Does the Overwatch competitive matchmaking prioritise grouping players of the same console together?

My duo and I both play on Switch, and on multiple occasions we've been grouped with 1-3 other Switch players on our team when the enemy had none. These matches are near impossible to win due to the hardware diff! I understand that one or two players having a 30fps cap will cause some difficulties, but when almost the entire team has these limitations and the enemy team doesn't? It just seems unfair and you can feel the difference in performance.

I don't expect to climb very far in my rank due to those very same hardware limitations, but I at least want a fair chance in my competitive matches.

Has anyone else noticed this happening in their games, or am I just unlucky?
