As the title says, i can't activate cross save. The reason is: there's an old Xbox account associated, on an old hotmail account that i don't use and i don't remember the password anymore. So it appears i can't disassociate the Xbox account and proceed with the cross save activation. What do i do?
I would suggest trying to recover your login information for the old account. If you are unable to do so and you wish to set up cross-save, your only option will be to create a new Bungie.net account and move all of your linked accounts that you wish to link together for cross-save to that new Bungie.net profile.
