Sega announced Android players of Sonic Dash may encounter issues with the game’s Global Challenge. Many players’ progress bar may not register the collection of presents on the track. It is suggested that you log out of Facebook if signed-in on Sonic Dash as a temporary solution to save progress. Some players have collected over 100 presents and say the bar hasn’t budged at all. Others claim creating a Google+ account solves the issue but there’s no official confirmation. The announcement was made around 1 PM Eastern Standard Time, so hopefully a permanent fix will come soon. There’s no word on this bug effecting iOS devices.
