Snapshot help

On the Duo X - I know how to add a snapshot directly on the device. But it won’t save. I tried going into Settings and choosing Current Pedalboard and save. But it doesn’t save it. I also tried connecting to the web gui and saving it there, but no luck there either. What am I missing?

Also, how can I use a MIDI controller to load the snapshots.

Hi,
Do you save the pedalboard after you create a snapshot ?
