In the last few days his has been happening. I cook miso on all 18 appliances. I check back every 2-3 hours and everything is normal. 6 1/2 hours into my miso I check back & see 2 of my aPpliances are empty when they all should be full. Wondering if it was a sync error or something. It's jus annoying when the 5th time u check on ur restaurant food on the appliances are missing. Anyone else experience this?
