Apparently you need your minecraft client to have marketplace,
but my java edition do not have any marketplace so i could not buy minecraft realm plus
I know how to get minecraft realm, but I want minecraft realm plus, it have more features and even auto backup.
I did clicked on https://www.minecraft.net/en-us/realms-plus
get realm plus button, but nothing happens, the website just reloads.
realms plus is the bedrock version, https://www.minecraft.net/en-us/realms-for-java/ is the java version
Java realms auto backups since it's introduction.
