Clouds saving and loading buffered samples on different slots problems

Hi all,
after many try, i get confused in how to save and load the buffered samples in the clouds
i really payed attention on how it is described in the manual
but after a reboot of the module, it seems that nothing is recorded…
i never see the green lights flashing in any slots…
do I miss sometjhing ?

When is the problem occurring (not seeing the green lights)?

when trying to save or when trying to reload a buffer?
