Lost all progress from season 7 update

Shanaynaybaby  The main issue here is the unblinking of accounts. Due to the way the linking works, it would have to be linked to the original one it was like to. If the progress is missing after you relink it - if you can to the original one, I'm afraid there is no way to restore that. That is part of what happens when accounts are delinked. Sometimes the system syncs it and loads the data again, but that is working as intended when progress is no longer there. If the progress went missing before you unlinked it, that is generally a sync issue or an overwrite in which case it would still be there but that unlink changes everything. We have no way to restore that data to what it was.
