Vampire Survivors won't get cross-save support on PlayStation 4/5 for now due to mysterious legal issues

Fans of Vampire Survivors on PS5 and PS4 may be disappointed to hear that developer Poncle has encountered mysterious legal issues that have all but ruled out the possibility of implementing cross-platform saving. This feature was supposed to be part of the April update and would allow players to transfer their progress between consoles, PC, and mobile devices.
Here's What We Know
Poncle had planned to add cross-save as a key feature of the April update, but recent legal difficulties have put this feature in doubt on Sony consoles.
The chances of implementing this feature on PlayStation are now very low, although the game team continues to work with Sony to resolve the issue.
Will Vampire Survivors be able to overcome the legal obstacles and implement this feature on PlayStation in the future? A good question that is unfortunately unanswered so far.
