GG Season Pass LVL 20 No Reward

Upon reaching the GG Season Pass Final Level 20, the 86 OVR GG FP was not received. The screen showed the XP being added to Level up to 20, but selecting advance merely took me back to the HUB. Viewing the GG Rewards shows Objectives Complete, but No Pack was rewarded. Closing game & restarting Xbox Series X did not resolve the issue
