No difference after uploading the Norwegian language pack.
Manual approach did not work for me.
The notice state under WordPress Updates: Button: “Update translations”
This notice was translated from norwegian “Oppdater oversettelser“
Each time you press the button, it looks like you have applied it, but a few seconds later it reverts with the same update.

Got 6 sites on two different hosts, same issue on both
– Will try manual approach and get back with results.
Same story here as well.
Got several sites on different hosts, same problem on all.
Update language and it appears with update again after a few seconds.
Using Norwegian translation on all of the sites.
There is no warnings or errors shown.
This started happening yesterday or today.
