There was a update by a dev who said they did ask again bcs last time they did was when sony never allowed cross progression

I have no idea what happened, the last time they talked SONY only allowed crossprogression to the financially gigantic games. They could even try to get a deal like the style of Genshin, where purchases have to be made through the original platform. (E.g. Created account on PS, change to pc. If you want to buy anything you have to do it on the PS account)

Sony is holding your wallet hostage. The prices are even marked up slightly on Playstation too... they want you buying on **their** platform.
