Since the last update, any achievements unlocked on Xbox are not being unlocked on PS4 when i use the cross-save. When unlocking the trophy in the PS4 and then going to Xbox, the achievements are unlocked with just a few minutes of gameplay. Before the last update i was playing on both consoles and unlocking the trophies/achievements with no problems. Does anyone else is having the same problems?

I've been playing on stadia of all things for the past few months because I couldn't access my ps4, I'm now discovering that although The console Can recognize I've got Excalibur and Mjolnir, it won't recognize I've killed the order of the ancients or finished hamptunscire

@ubi-keo I do not have the "England Subdued" (Complete Hamptunscire Arc) or "Disorder of the Ancients" (Eliminate all Targets of the Order of Ancients) trophies

However, as I have acquired Mjolnir, I do have the "Worthy" trophy, so the PSN trophy system has recognized that I own mjolnir and has given me the relevant trophy, however it has not recognized the 2 story trophies have also been achieved in order to do so.

In order to get Mjolnir, one needs Thors Cloak, an item earned by eliminating every Order member (so thats proof I should have that trophy), which in turn requires a target only accessible after the Hamptunscire arc (so thats proof I should have that trophy)

@ubi-keo i made a list of the trophies that have not unlocked in the PS4. In Xbox i get all of them so theres nothing else to do in England map. I've tried to get some of those who are not related to the story again but even so most of them don't get unlocked.
That's the list:

The Enemy of My Enemy
As It Was Foretold
England Subdued
Disorder of the Ancients
Old School Treasure Hunt
Skadi's Hobby
Overdesign II
Completionist All the Way!
Row Rage
Home Sweet Home
Not the Norse You're Looking For
Ultimate Refinement
Flying Eivor
Good Catch!
Is There Anybody Out There?
Full Mastery
Slam Master
The Hidden Truth
Master Hunter

@ubi-keo OMG i broke up with Petra to date Randvi after the endgame hahaha.
But the good news are that i find an old save in wich i didn't have killed the entire order of Ancients. So i killed them again and at the end, all thropies related to the main story have been unlocked.
Now only these are missing:

Master Hunter
The Hidden Truth
Completionist All the Way!
Those are the ones i didn't find a way to get them again. I'll try in that old save i mentioned, but i'm not sure if i have already completed Master Hunter in this save.

Overdesign II
For this one i've tried some different ways for completing it again, but even recurring to some videos i couldnt get him

Flying Eivor
Old School Treasure Hunt
Row Rage
I havent tried these yet, but they are pretty simple so i'll let them for later

@ubi-keo Hi, just as an update the problem has seemingly solved itself

I didn't have any main or side quests left really, so I was concerned I wouldn't be able to do as you suggested, but I played again on my ps4 last night for a few hours and both trophies just popped up as complete, seemingly at random

@ubi-keo I think I had just completed a reda daily quest, I *think* it was the thieves couple one, but it was also the 2nd of those I had done that evening, so I'm not sure that completing the quest actually caused the trophies to pop
