Assassin's Creed Syndicate achievement on xss cannot be completed

thanks for your reply, I will try to contact the game support. If I have any questions I may need to trouble you later

Hi! I'm Rostom, an Independent Advisor. I will be glad to help you here.

Does it only happen to that particular game?

Please make sure that you read the description for the achievement or challenge carefully. You may have to unlock a combination of achievements or challenges to unlock your rewards.

Some achievements may take up to 72 hours to appear online. I would advise to wait until that given time.

I have tried all the methods mentioned in it, but the first three achievements have reached the requirement for more than 72 hours, but they are not unlocked correctly

Thanks again for your answer.

To add, I can unlock other achievements in the same game later, but I replay the game progress of Sequence Nine, and the two achievements shall we dance and mentor still cannot be completed

I appreciate your effort in trying those methods. Thank you for the additional information. So you have re-played the other games and same issue. This may have something to do with the game itself already. It may be an issue from their server validating your achievements. In this case, I suggest that you try to contact the game support which is Ubisoft here https://support.ubisoft.com for further investigation into this matter.
