I upgraded from an XS Max to a 15 Pro, when I sign in I get the accounts from my previous mobile, but when I try and add new accounts I get asked to "Replace previously saved accounts" which further states "You're about to delete all accounts previously saved from this Device: iPhone XS Max. You'll replace them with accounts on this device: iPhone 16,1"
Does this mean it will delete all my accounts and I'll be restricted to the accounts I added at that time? This is also the same prompt I get when trying to back up the accounts.
