Hey there , I recently noticed that if you are upgrading your champion's mastery level in "Loot" there is no animation for it. I've done 2 mastery upgrades , one level 6 and one level 7 and none of them have animations however it displays correct (upgraded) mastery level for that champion in "Collection".
BlueNinja891 votesIf your client is set to "Low Spec" mode then there will be no fancy animations for any sort of level up.
This includes Account Level, Rank Level, Honor Level, and Mastery Level.
It will also disable chest and capsule opening animations.

herbiko042 votesI understand , but all animations are enabled in my client and it worked properly before 9.7 (I'm not sure about patch but it happened recently).

KoggyStyle1 votesim not in low spec mode, im seeing capsule animations, however ranking up in mastery even from 4 - 5 etc is not working for me.
EDIT: its just a visual bug, the champs are ranking up.
Silky Stars1 votesI just had the same issue as well without being in "Low Spec". The champion is the correct master level but the animation didn't play in the loot area, even though I get other animations.
herbiko041 votesyea , they are probbably going to fix it <3
