Got the Now Bar on my AOD , watching the United game and the Now Bar is about 30 minutes behind , 45 minutes had gone but the Now Bar had 15 minutes gone in the game ! Battery optimisation is turned off for the Google app as well.....
Mines the same, spurs are still 0-0 on mine too, I think its a Google problem rather than a samsung problem, works fine some days but not today, think it depends how often google updates them
