I had previously posted on here about my missing trophies from my PS4>PS5 upgrade, these were what I was missing:

calling in a favour
as it was foretold 
disorder of the ancients
skadi’s hobby
Silent Viking 
completionist all the way
builder
Home sweet home
Ultimate refinement
Flying Eivor
orlog Champion

I booted the game up for the first time in about a month today to have a mess around and check the river raids and I managed to unlock 2 of the above.

Disorder of the ancients - popped after I assassinated a dummy by the Assassin cabin at base camp

Ultimate refinement - popped after I maxed a random weapon

This is a start but some of the ones listed above are far, far too time consuming to start again (I.e. completionist all the way and home sweet home) and we shouldn’t need to be doing random instances like this just to try sorting out our trophy lists.

Is this still being treated as an active problem? I have looked through the list of known issues and can’t see anything about it being investigated.
