Starting from 1st August amazon will require all developer's applications to use a new way of downloading orders. Salestio is already using this integration since April.

However, if you are using Salestio prior to April, then it may happen that you need to re-connect your amazon account to continue importing orders to the e-commerce store.

If you receive an email from Salestio, please re-connect your amazon account.

More details you can find in our blog post — https://salest.io/blog/page/changing-in-syncing-amazon-orders
