Link to mod response on an earlier post:
They did not get a warning or sent messages by anyone. PS just requires it, and they missed it before. PS probably did get the warnings, and why they require it for their games though ;)
To be clear; No-one got a warning, and PlayStation wasn’t involved. I just brought it up as we initially became aware of the issue when wanting to release on PlayStation, but this one slipped by, I guess.
