Hi.
I am having an issue with trophies not unlocking when I play on a different PS4 than my main console. I am out of town playing Overwatch on my boyfriend's brother's PS4 and I mostly play Mercy. I finally got a quad res and was quite upset when the trophy didn't pop up for it. I even got Play of the Game and Legendary status with 10 votes for it! I already contacted Blizzard about it but they said the trophy unlocking is out of their hands and I have to contact Sony.
I have also had this issue with Diablo 3. When I first started playing that I was playing local co-op on my boyfriend's PS4, but then when I bought my own copy of the game and started playing again some of the trophies were glitched out. I had to delete my save file and start a new one to get those trophies. For example, I currently have the trophy "Dream Team" for having 6 characters, one of each class, at level 70 but I still do NOT have the trophy "Above & Beyond" for reaching level 70 with only 1 character.
Apparently I am not the only one with the issue. This post onBattle.net is similar to the issue I was having on Diablo 3: http://us.battle.net/d3/en/forum/topic/14058407056
But it looks as if this is an issue for Overwatch as well. I don't know if this is a syncing issue with Blizzard servers or Sony PSN across multiple PS4 consoles or a combination of the 2 but it is quite frustrating 
Some help on this issue would be greatly appreciated.
