Good catch on the upgrade path: that 'not saving the key' prompt usually means the new AppImage can't reach the keyring entry (KWallet or Secret Service) the old build wrote, often because the app identity or sandboxing changed. Before upgrading again, back up the key or seed from the old version, then check whether the keyring entry still exists. Keys kept on your own device, not on a company's servers, are the self-custody model that holds up when apps change. Jack — app.superaiwallet.com/wallet
