From the SDK team;

After looking at the FOTA Download library for a bit I am not convinced it was ever meant to support download resumption after reboot. Even before the change to using hashes to check if the file is the same, there wasn’t anything stored anywhere persistent to be able to resume the download. It might have worked before by coincidence though.

The setting the customer talks about is from the DFU Target library which is used by the FOTA Download library. The DFU Target library does support resumption after reboot and that feature seems to work on NCS 3.1.0

Thanks,

I would note, what I didn't notice when I posted this, is that those variables are declared as static, so they definitely aren't being assigned in another file.

For the minute I have commented out the static declaration, and then externed them in my code so I can manually save and recall them in flash.
