Matching Error (Ex: Error 8541)
You try to send your products by sending the product feed (creation), but you get in the report an error message like this one:

This is a classic correspondence error (or matching in the jargon).
That means that your product is considered as existing but is rejected by the Amazon automaton which has established that the product that exists in the database does not match the product you have sent.
There may be several reasons:
Title dis-concordances, manufacturers, supplier references etc. Products having multiple EAN codes Different attributes, such as Amazon: Gray Color, Shopify: Grey Color
It just happens sometimes that a bad use is made of EAN codes, and one of your colleagues has created a product with an EAN code that does not match the product. In this case, you must use mediation with Amazon, demonstrate to Amazon your good faith, and claim ownership of the product.
It is difficult to match its own products with existing ones on Amazon when there is an error in matching, but there are solutions:

This will update the ASIN in the App, then, go to Action > Catalog > Export and send again the product.
OR
