Zeus v13.2.2: update permanently erases wallet data in iCloud Keychain; devices opened later will lose their settings

Zeus developers report that, because of a bug in a third-party dependency, older versions stored wallet data, including seeds and connection credentials, in the keychain synced through iCloud instead of local device storage. Version v13.2.2 moves this data to local storage and then automatically and permanently deletes the iCloud copies without asking for confirmation. The deletion propagates to all devices with the same Apple ID: any device that has not yet been opened on v13.2.2 will lose its saved wallet configurations, because older versions had no separate local copy. This also affects devices that updated in the background; changing the update order does not avoid the problem. According to the vendor, iCloud Keychain is end-to-end encrypted, the data was accessible only to the user's own trusted devices, and there is no evidence of a user data leak.
