I have a node.js based custom app accessing/updating the store’s customers’ notes. It suddenly stopped working without any change on my side neither in the store nor in the node.js server. Looking for somebody who can help solving the issue.

If you could provide code access, I could have a look.

Can you drop me a personal note to contact@betterplay.ai. We can discuss further. Thanks
