Poncle Games has announced that the PlayStation versions of Vampire Survivors will not have the Cross-Save function due to a legal issue. This legal issue is that the cross-save function on PlayStation Poncle would need to share partner information, something the studio says it cannot share. There is still a miniscule chance that Cross-Save will continue along the line, but this requires more discussion with PlayStation. The full explanation is below.

PS: For anyone who wants Cross-Save, only to unlock trophies, it is worth noting that PS trophies are automatically disabled at a platform level for all games when using a storage file from another platform “
The Cross-Save function still comes to PC, Xbox, Android and iOS in the next game update. It will also be available on the switch later.
