Same here no one seems to want help either been day or 2 now and it just wont work but i can access areas on SP that overs cant before its installed.
Same issue here i can access areas i shouldnt be able to unless its fully installed and just saying its not for the MP. Tried reinstalling and stuff a few times and it doesnt seem to want to "Fully" install"...
i spent a long time on this issue, the only sure fix is to go to settings -> psn -> activate as primary ps4 then decativate. log back in and repeat but this time activate your ps4 as primary. I am not sure why it works but I have had success on two systems with this method.
