In February 2020, the Chinese marketplace introduced a new game in the AliExpress mobile app called “Friendship Coupon”. It is another interactive game that can be used to earn coupons by applying them to any product.
Not long after the release of the game, shoppers started complaining about the error on AliExpress. The error only pops up when the user tries to get a friendship coupon. Let’s look into why such a notification appears.
Causes of 9001 error
The most important reason why you see 9001 Error on AliExpress is because you have multiple accounts. The algorithms of the online shop assume that the user wants to invite himself for coupons, so it blocks you from accessing the option. This is the reason why you see the “Use a different device to log in” notification on AliExpress when the 9001 error occurs. In general, you should not register multiple accounts via the mobile app or the marketplace website. These are all fixed by the algorithms. If you only have one account, but there is an error, the reasons for the error may be as follows:
- The option is temporarily unavailable by Aliexpress’ decision. Some interactives temporarily stop working due to technical problems on the Marketplace side, or deliberate disconnection;
- You access your personal account using your social network account. Buyers who log in this way often encounter incomprehensible errors;
- You have an outdated version of the program. The app is updated quite often so it’s easy to miss the next update;
- You are a new user who has not ordered anything on AliExpress yet. According to the rules, only users who have already made purchases can earn coupons.
These are the main reasons why you see the “Use a different device” error on AliExpress.
How to remove the 9001 error
You can bypass the error by simply opening the invitation link in your browser. In the browser version of the game, users do not encounter the error code 9001 on Aliexpress.
If nothing works to resolve the error, you should write to support. Only technical support has the most up-to-date information related to the operation of the marketplace.
