According to the PlayStation Blog, they confirmed that we’ll finally be able to change the PSN Online ID in PS4.
As PlayStation mentioned back when they first announced the feature, the ID change feature will only be compatible with PS4 games originally published after April 1, 2018
However, PlayStation’s most recent update did warn that it had found “an instance where a game did not fully support the feature, even though it was originally published after April 1, 2018.”
If you want to check out a list of the officially tested games for yourself before making a change to your ID, you can head here. PlayStation claims that “the large majority of most actively played PS4 games support the feature.”
Before you fully commit to changing your ID, you should make yourself aware of the some of the potential issues you could run into with the games that haven’t been tested.
