Same here and support told me "Yeah we know, okay bye now." Great system

Yeah same.

My constructed rank for June is not updating after each match (neither wins nor losses are changing my rank). Additionally, in the past an animation would play after each match showing the change in rank - it is no longer appearing.

I play standard events in B01. Yesterday for example I won 3 matches and lost 1.
In my profile it is always marked "bronze 4" and indicate that I must do at least one game to get the reward. Which proves that the game does not take my matches into account.

Last month I worked my way to Mythic rank. This month I have been playing and it started on Platinum tier 4. However, whether I win or lose the ranking meter doesn't appear and I am unable to rank up or derank. Please advise what I should do.

Same, multiple wins and rank is not changing.

Same. Multiple wins at Gold 4 have shown a pip going down after victory. Rank not changing, in fact, going down.

This is also happening to me on platinum 4.

My rank is not changing I am stuck at Bronze Tier 2

Last night, I played "Traditional standard Ranked" (My rank was "Gold Tier1")
After wining match, constructed rank show "Gold Tier1" instead of "Platinum Tier4".
I want you to change my rank.

Thank you.
