I am not sure if this is an issue with the nRF Connect extension or the my Thingy91 but when I use the "Flash" button in the actions tab of the NRF Connect extension to program the Thingy91 the action fails and I get the following output :
* Executing task: nRF Connect: Flash: hello-world/build

I have also attempted to program the board using the nrfutil tool straight from the terminal which does work however I notice that when i try to program it with a merged.hex file it fails but when i use a zephyr.signed.hex it succeeded. You can view the results below:

So using this information i attempted to modify the file C:\ncs\v3.1.1\bootloader\mcuboot\samples\zephyr\hello-world\build\generated_nrfutil_batch.json however due to the fact that it is a generated file the changes were overwritten.
I have tried bootloader mode as well that does not help with the NRF Connect extension but did help with programing using nrfutil tool.
Any help in getting the button in the NRF connect extension to work correctly is appreciated. Many thanks.
