This has been going on for most people that has bought Java in the past few months and it is happening with me also. When I bought the Java and Bedrock bundle from Minecraft Launcher it never said I bought Java and Bedrock and it is still locked, but under my microsoft account I own it and should be able to play it but when I try to launch Java from the microsoft store, it gives me the pop up to launch Java from MCL and when I click on the pop up for it to take me to the launcher, it just takes me to the xbox store to buy MCL even though I already own MCL and Java. This is not an in game bug but it is a bug with Java that needs to be fixed. I think this is only happening with windows I don't know for sure but it really needs fixing, I only bought MC for my PC for Java.
