I have completed the Exodus 2A master lost sector solo at LEAST 20 times now, attempting to get platinum rewards during each run. Upon killing all champions, no banner shows up along the bottom in regards to platinum rewards, no "Champion Rewards: Platinum" in the feed on the left, and I often receive nothing but some solstice keys. If 1 champion is left alive, the banner sometimes accurately shows Gold Rewards. If 2 are left alive, sometimes a Silver Rewards banner shows. Is the game not registering the platinum completion at all and therefore not giving any rewards? I have gotten no exotics across all of these runs and 95% of them have given me nothing other than solstice keys.
