This needs to be added as a new feature or a workaround.
It has been reported internally.
It is also discussed in this thread with some additional information as well: https://devzone.nordicsemi.com/f/nordic-q-a/63085/a-gps-download-fails-mid-session

Hi Tron,

This depends on the network your device is connected to, but generally no, TCP and NB-IoT do not work great together.

(Most networks do not block TCP on NB-IoT by default, but can drop TCP packets when there is too much strain on the network traffic. e.g. I tested the GPS with SUPL sample on the NB-IoT network and it worked).

I will need to do some investigations with regards to your last questions.

BR,
