[Wild] I don't receive stars when winning

When I win a match, I get stuck on the "Blurry background, fireworks, nothing written . (idk how to upload a screenshot)

I don’t get the stars animations either, just the fireworks

I have to exit the game and come back.
NO matter how long I wait after the win, I never get the stars to progress ranks (stuck at gold5, 1 star)

Is this a known bug ? how to fix this is really annoying

Note : It works perfectly when I lose
