Recommended Actions:

1. Check the Notifications tab for the channel, this will show any recent errors, which might bear fruit give you a steer or further questions to ask / check.

2. A Common problem for Shopify channels is not having a Location specified on the Channel setup.

This cannot be done when a channel is first added as the Locations need to be downloaded from Shopify once the channel is syncing.

So its something the users must come back to and update.

If not specified, when Channels 2.0 talk to Shopify we will be unable to send the stock level information and it will fail with an error message.

(We plan to add a warning message when saving Shopify channels in a future release).
