Very true. Unfortunately for me, it wasn't created yet when I did most of my firmware changes. So it's 'habit' now, that brings me to use DfuSE.
Your reminder will help me remember to use NanoVNA-App. Although new firmware versions are slower in coming, these days.
(I also have & use a NanoVNA-F. To upload firmware to it, one only needs to copy the file to the Nano with Windows Explorer.)
