If you were having issues with cloud saves for Minecraft on Switch, this was due to a backend error - not intentionally disabled! Should be good to go now.
If you're still having issues, try this: 1. Go to [System Settings]-> [Data Management] ->[Save Data Cloud] 2. Select a profile that has Nintendo Switch Online 3. Press [Y: Update List] while [All Save Data] is selected.
