Since last Friday, March 13, I've been having issues with the leaderborards in Grid for Xbox one. At first I could not access them at all. That seemed to have been corrected. Then as I was attempting to run fast laps at tracks I like in cars I enjoy driving, sometimes the lap time would not post. This appeared to be random at first. Then it seemed to be happening to a specific car I was using, the McLaren M8D. Now today I am able to see previous laps that I have posted but am unable to post new times at tracks where I have not previously posted times in specific vehicle categories. I've tried different car categories at new tracks and am currently unable to post any new times. I would appreciate any help on this subject, thank you.
