miHoYo has revealed on the official Twitter that Genshin Impact will not support cross-progression on PlayStation 4.
However, players can still invite or join the session with friends on the other platforms e.g. PC or mobiles. Although there is no detail on how the feature was ditched, it seems like PlayStation 4 has some exclusive items which are not available elsewhere.
This information is important as there was a speculation that the game would support cross-progression over the platforms.
Therefore, it is suggested that players will need to plan if they are going to play on which system as the save from PC and mobile versions cannot be transferred to the PlayStation 4.
Genshin Impact will be launching on PlayStation 4, PC and mobile devices on September 28th, 2020 as a free-to-play title.
The game will also be available on Nintendo Switch later this year, too.
