RE: Issue with Missing #MQTTEVT After MQTT Connection on nRF9160

I'm not sure what caused the issue, but my workaround was to wait specifically for the MQTTEVT message. It wasn't a proper fix, but it worked.

Could there be an issue with your network/signal strength? Could you please provide a modem trace from your device?
