We're continuing to see problems with eBay this evening and are looking forward to an update from the eBay team.
You may see an error like the following from eBay during this time....
"Sorry, something went wrong. Please wait a moment and try again."
Most stores are able to sync intermittently. If your store is particularly affected, as in it is unable to sync for more than 4 hours at a time please reach out to our team so we may investigate your store's interactions with the eBay API.
