DBs and GR key drop chance nerfed on t16?

Deaths Breaths and Greater Rift Keys arent dropping in t16 from the mobs that should be dropping them on every kill.

I have never witnessed this type of bug and ive been playing for the past 29 seasons. Can someone from Blizzard Support help look into why DBs and GR keys arent dropping regularly from the mobs that should always be dropping them on Torment 16 difficulty???

Thank you so much!!!
