Hi,
In our app, we have updated from NCS 1.3 to 1.4 and suddenly calling bsd_shutdown() blocks the whole application for up to 10 minutes. Probably it is now waiting on something in the new version but we are unable to find the reason. Could you please tell us what changed since the 1.3 that might be blocking the app? Unfortunately, we cannot provide a modem trace because it is running on our custom board with no UART output.
