limited rank did not raise with a victory but i lost one pip of cunstructed rank
I just won a sealed match, it showed the victory animation and said my limited rank was Plat 2 which is actually my constructed rank, then the animation played for loosing a pip of rank and when i checked my profile i actually lost the pip in constructed.

Same, lost pips on my limited rank after a victory. completed the sealed event with 7 wins and stayed at the same ranking.

Same. My limited rank is not changing with wins/losses.
It shows my constructed rank changing instead. -

I just had the same problem.

I had something similar:
First, losing a brawl match caused me to lose a pip in limited (although it labeled it as constructed).
Then, winning a sealed match caused me to lose a pip in limited.
