Language Reactor Error: Failed to retrieve linguistic data: NETWORK_ERROR Lang: ru

Error updating saved items keys.

I have already tried restarting browser and computer as well as reinstalling the extension. I hope this report reaches everyone in good health, and I appreciate any and all help.

might be a server bug. works fine on my end now. could you tell me if it persists?
