Cause
Sometimes you can’t publish even if you managed to connect your Etsy account. There are multiple reason for this, each one with a corresponding solution.
Solution 1: Complete the required information
Some of the information may be still missing. To ensure that you are authorized to publish products on Etsy, try to list a test product directly in Etsy before bulk publishing with Nembol.
Solution 2: You probably logged in some time ago
Please log-out and log back in. Credentials and tokens expire. For your security. The duration of the token does not depend on Nembol: it is set by each channel and there is nothing Nembol can do about it.
