I'm sorry to hear that you are experiencing issues with the Ubisoft Connect challenges.
@gatton16 @Domboyy @Xadro_ Could you please provide a video showing you completing the actions required for the weekly challenge. After you have done that wait a couple of minutes then open Ubisoft Connect to show it has not been counted.
@Sib3riX @alkiww @Merkury90 Are you experiencing this with certain core challenges or all that you have tried? If it is certain ones could you please provide a list of the ones you are experiencing issues with.
@Spyder_Bait I can confirm this is a known issue, could you please post on the mega thread we have created for that particular issue here.
@killerkerney Could you confirm if you are experiencing issues with the core challenges, weekly challenges or both?
