Wallet of Satoshi. Some troubles revealed

Wallet of Satoshi
App Version 3.3.6 (352), iOS 26.6

This information complements the website information from the WoS official website and I think may be useful to those who also encounter similar problems.

The custodial wallet runs with a direct connection with the Belarusian IP address. But the self-custodial wallet only runs via VPN! And I couldn't switch the wallet to non-custodial wallet without VPN.

Custodial Wallet

Switch between custodial and self-custodial wallet without VPN freezes at three-quarters part.

Self-custodial Wallet

Wallet of Satoshi stuck without VPN at startup during Syncing... at three quarters.
If self-custodial wallet was once initialized it is possible to return to custodial wallet by menu.

If self-custodial wallet was not once initialized on device, this state of the application can only be overcome either by restoring the self-custodial wallet of Satoshi, if it was already once created before, or by reinstalling the application.
Force-closing the app and restarting leads to nothing new, the app starts in the same state.

If the VPN connection is dropped or you disconnect, Wallet of Satoshi gives out the message: "A network error occured. Please check your connection."
The message disappears when the VPN is restored.

Switching from WoS Custody Wallet to Self-custodial wallet without VPN stuck the app on the Finalizing... at the eleventh of twelve parts of circle.
