Ok , as I said - to fix something we need to see that issue , could you please give us an example of such product?
I have already provided several examples to your team and was told that the Auto Update function works as intended. If it was only me having an issue, then I would accept it and move on, however looking at this thread and other posts in the forum it is very clear that other users are also experiencing the same issue with Auto Update.
Actually it should not be that difficult to reproduce the issue on your end and test it for yourself - with my store it happens almost every day, or every two days. I have at least one product that has an incorrect price after Ali Express suppliers change prices on their end.
Example: today one of the suppliers has reduced the price of a product from $40 to $20. On my store price is properly reflected on my home page/category page but when I access the page for the product in question it still has the original price, not the reduced one. In this case it won't be that much big of a deal, but the other way around is also possible, has happened to me and may lead to profit loss - supplier ends an ongoing promotion and from 20$ product is back to $40. On my store however this is not reflected after auto update and if someone buys it I won't be making any profit out of it.
So please can someone in your team look into it? This feature was actually the main selling point for me and it doesn't feel good to find out it does not work properly.
