How to link PS5/PC/Mobile accounts for cross-platform play?

To link accounts for cross-platform play: 1) Go to Settings > Account Center > Link Account; 2) Bind all login methods (Google, email, PSN) to the same account; 3) Once linked, log in with any bound method on any platform to sync progress. If you accidentally created separate accounts on different platforms, contact official support at [email protected] with both UIDs to request account merging.
