We all know how frustrating it is that Switch owners have no way to transfer or backup save data yet. Some have been under the impression that Nintendo support has tools to transfer or recover Switch save data.
But, if this Polygon report is correct, not even Nintendo themselves has that ability yet.
Basically, if you have a Switch with a problem of some kind, and also have some significant game saves on it, DO NOT send it to Nintendo for a replacement yet. Because it will probably mean losing all that hard won progress, forever.
This really is bad, and needs to get as much exposure as possible, because Nintendo should be ashamed and embarrassed on behalf of their customers. And I say that as someone who loves Nintendo and the Switch.
