For about the past 2 months I have not received my challenge rift rewards. It may have to do with a platform upgrade from an Xbox One Series X to an Xbox X. After the switch, I lost my account history and had to start over on my primary (of 3) Microsoft Hotmail accounts on my Xbox. No big deal. I only play seasonals. Also, I purchased D3 full version digital so I could pull the disc and donate it. That seems to have worked just fine. I am experiencing the missing rewards on the 2 “Hotmail” profiles into which I have logged in thus far. I think I’ve received 1 reward over the past 2 months, and that happened about 3 weeks after I posted that I was not receiving rewards, so I thought that was due to some action from Blizzard.
