I have just started testing out all the functions of the E1 MKII.
I have successfully made, renamed and exported a few snapshots from the E1 MKII to my desktop.
I am, however, unable to get the snapshots to import into the Web Editor and therefore unable to get them to show in the E1.

E1 MK11 latest firmware
I also had this problem, and discovered that snapshots are tied to a particular version of an E1 preset. If you make and download a snapshot using one version, it will not import to an updated version of the preset. At least, this is what I have found using the K4r preset, and have not tried on others.
Downloading and reimporting snapshots to the same version of the K4r preset works properly.
If a new updated version of a preset is loaded to the same E1 slot, the existing snapshots will disappear.
