Why did the system return "Fail to get product information" when importing compatibility fitment table from an eBay listing of other sellers?

The reason for "Fail to get product  information" might be these
1. eBay token is invalid, please update the first eBay API token of ALL(every) your eBay accounts
2. This listing does not have a fitment table, the table you see on eBay is related to the GTIN of that listing, so there is nothing to import
3. eBay is experiencing technical difficulty, please retry later
