Q: Sometimes I log into another eBay account, that is not in sku grid, what happens to the extension if not logged into the right account?
A: If you happen to log into a different eBay account that is not linked to the sku grid account and the chrome extension, then yes, when it tries to revise the item and you're logged into the wrong eBay account, the changes would be sent to file exchange but will pertain to the wrong eBay account and therefore, that eBay account will not process the changes through file exchange because 1 eBay account cannot revise items that do not belong to it. To avoid this, it would be recommended that instead of logging into the same browser session for a different eBay account, either open up an incognito window and open the 2nd eBay account there or just use a totally different browser (i.e. if you're using chrome with the extension, then use firefox for the 2nd eBay account that isn't related).
