Strange, just tested mine and it’s giving me the expected result (orders from 2021 and 2020), test query below:
customer(customerAccessToken: $customerAccessToken) {
orders(first: 100, reverse: true) {
edges {
node {
id
orderNumber
processedAt
}
}
}
}
Using the xx.myshopify.com/api/2021-01/graphql.json endpoint.
