Giving up

I had two legacy Minecraft accounts.  Both were used by my daughters, who didn't have any online presence when I bought them.  I am now being forced to migrate them to these Microsoft accounts, and have been unable to do so.  After an incredible amount of frustration, I am giving up.  We are no longer playing Minecraft in this house.  Everything about your security system is a roadblock to my kids playing your game.  It is ridiculous.  I don't expect anything to change; I just wanted to futilely yell at the clouds because this is a game we bought a long time ago and now can no longer access because of all of the extra login / account / "security" features.
