I start the game, i was just playing a couple of days ago and now ubiplay can't connect to my achievements. Not sure what has changed since the last time I played
Thank you for reporting this to us, NomDeploom, we're sorry to hear you were encountering that.
Just to confirm, with these failed to sync errors there should be an option to skip past this and get into the game, if you do so are you missing any progress?
