I have the no-battery refill carts. I have not hit a refill point. I have removed all cartridges with power on. disconnected from wall for 15min. Turned back on and re-insterted all carts. LK says “not recognized”. When I install them individually and close lid to check each one installed, LK appears to be working until all cartridges are reinstall. Then it goes back to “not recognized” status.
We’ll send a replacement LK Monday.
