We bought PS4 & Minecraft (physical disc) a while ago. Pretty soon Minecraft got an update to Bedrock edition. However, the kids would prefer to play the old PS4 edition -> is there way to access the PS4 edition after upgrade?
Revert approach: We were able to revert to PS4 edition by deleting Minecraft, removing network access and installing Minecraft again from the physical disc. However, this setup is quite fragile.
Accessing PS4 Edition from Bedrock edition: Kids told that their friends have been able to play PS4 edition from Bedrock edition. From https://minecraft.gamepedia.com/PlayStation_4_Edition I found
PlayStation 4 Edition is a separate game from Bedrock Edition and is still playable for anyone who owns it by selecting the "Editions" button on the title screen of Bedrock Edition.
However, I haven't found "Editions" button on the title screen?
