Just checking again to see if anyone is also having this issue. I achieved the maximum streak bonus from Survival competitive (all 5 boxes were filled) but I still didn't receive the triumph. If you do the math in the image above you can see that it does in fact add up to the win streak bonus (-2 loss, +1 win). Am I missing something here? Does it say "achieve the maximum win streak bonus" but it really means "literally win 5 matches in a row, different from 5 win streak?"
