DSers Registration Issue: Unable to Import Products

I’m unable to open DSers on any of my Shopify accounts. Every time I register on DSers, the registration is successful, but AliExpress asks for phone number verification and always displays a “System error” (see attached screenshot). Is anyone else experiencing this issue with DSers? This problem is preventing me from importing products from AliExpress to my store, and DSers is the best free app for importing products.
