Hi there! The purchase of Silver triggers a 90 day cooldown where Cross Save cannot be deactivated. If you recently deactivated Cross Save, all of the accounts associated with that Cross Save cannot be reactivated for Cross Save for 90 days as well. For more information, please review the Cross Save Guide, linked below. https://help.bungie.net/hc/en-us/articles/360049498031-Destiny-2-Cross-Save-Guide
