My friend does not appear in the friends list in Minecraft preview

Additionally, if my friend sends me a request and I accept it, it puts me back into the normal version and I get the 'Your Client is Out of Date' error, which prevents me from playing.

Additionally, please fix the invite system so that when a request is sent from the preview, it puts the recipient in the preview version as well.
