SL highest team player MMR not working

I was hopefull when i read this in latest patch notes:

“When queued as a party, Storm League now looks for matches based solely on the higest player’s MMR.”

Unfortunately, it simply does not work.

I would link to loading screens but apparently im not allowed to show links.

The plat curse continues. Just like last season and the season before and so on… As does the race to master in plat by diamond / gold team combos.
