double rewards are not being rewarded after watching the ad. I compared my xp bar before and after wins and not once has the xp for that fight doubled. Before a fight I was at 473 xp, won the fight that reward 109 xp. I watched an ad to double my rewards which should have been 218 xp earned. Instead after viewing my profile in the menu my xp only read 582 xp, which means I was only rewarded 109 xp instead of the 218 xp that I watched an ad for.
