Errors with the plug in and downloading/updating products

I have tried to update my Key this morning as I have just repurchased an updated premium license.

I go in and add it and its says its authroised and good to go. As soon as I hit save the key goes back to my old one.

I am trying to update a number of products and add new ones to my site. If I select overide I get the told the item is not found (the link is https://www.aliexpress.com/item/1005005385418786.html so its valid)

If I go to add new products in via google I click on import and it says “Can not retrieve data. Service unavailable. Please try again later.” The website is authorised in the google plugin.

Please advise how this can be fixed so i can start importing products again. Please note the issues of importing were happening BEFORE i updated – I though updating my license would help solve the issue.
