DFU failing with nRF Toolbox when updating to Samsung S10 on Android 10 (works on other devices).

We are currently having an issue with DFU failing on Samsung S10 running andorid 10. We are using nRF Toolbox for BLE and it appears to connect to the bootloader, but then fails on the second re-connect attempt to transfer the firmware.zip. I believe this issue is due to the direct advertisement report is not being received?

Hi,

Which SDK version do you use?

I believe this issue is due to the direct advertisement report is not being received?

The SDK bootloader examples do not use directed advertising, and I do see a good reason for doing it. Have you modified the SDK bootloader to do this? If so, why?
