The .conf file, I think it is a WireGuard config, right?
Could you please DM the unsupported config file to me, I will test it, thanks.
Usually the standard WireGuard config file is supported by the app.
The config file will save in router if it import via web Admin Panel, it will save in phone if it import via app. Our future versions will support connecting the configuration saved on the router on the app.
