Please can somebody else try to reproduce this situation explained in this issue with Zeus and NWC accounts?
https://github.com/ZeusLN/zeus/issues/3463

You may use 2 devices or a mobile device with Zeus as NWC server and a desktop with Alby extension as NWC client.

Create a NWC account in Zeus, add it into a client NWC app and make some payments.

If you use as "NWC server" a GrapheneOS, you can extract all Zeus app logs, provided by graphene in a easy way:

• keep the Zeus app open while you are messing around with the "NWC client" device
• go and consult the txs history log in the client device
• watch if the NWC server device crashed
• if crashed, long press Zeus icon - app info - view logs

You can export the entire app logs into a file and look for specific errors, why it crashed or will be helpful to post that log in the Github issue. No worry, there's no personal information in that log, is just technical stuff about the app.

This is NOT the lnd log that you can export from within Zeus app! Is a device OS app log.

But first of all I am curious if somebody else have this problem using Zeus as NWC server with a sub-account.
