Split tunneling is not available by IP/hostname for imported WG config on macOS client: "default server does not support split tunneling function"

[softhoz]

Describe the bug
Split tunneling is not available by IP/hostname for imported WG config on macOS client: "default server does not support split tunneling function". I have a hosted WG server and imported client config to amneziaVPN client. It works fine, but split tunneling is not available at all.

To Reproduce
Steps to reproduce the behavior:

1. Open AmneziaVPN client
2. Click on '+' button
3. Click 'File with connection settings' to import your WG config file
4. Select config file for import and enable WG obfuscation
5. Click 'Split tunneling enabled' button on the 'Connect' screen with the newly imported config
6. Check that 'Split tunneling on the server' has status 'Enabled'
7. Click 'Site-based split tunneling'

Expected behavior
Toggle switch is available and hostname/IPs can be added to the list

Actual behavior
Toggle switch is grey, warning pop-ups "default server does not support split tunneling function"

Screenshots

Desktop (please complete the following information):

• OS: macOS Sequoia 15.2 on Apple M4

** AmneziaVPN client version

• 4.8.2.3

Additional context
AllowedIPs options in the WG client config do not work as well, allowed IPs (other than 0.0.0.0/0) become unreachable and other IPs work but with no tunneling at all
