You can face with this issue after update, the possible reasons are:

  • AliExpress supplier changed variation's names and plugin can't update product because the existing names are different from those which were used before. 
  • AliExpress supplier added or deleted some variations/attributes and plugin can't correlate them with the existing ones.

How to resolve:

  • Reset product: go to Product -> Supplier -> Reset -> Update Product: variations will be reset. 

Then go to Update and click Update Product:  

DONE!
