I’m using GS 9.8 and when I tried to add a new account in settings using the + symbol, as it opens eBay in the GS browser, it gives the error “The eBay account for the user (my ebay username) was authorized multiple times. The duplicate will be deleted.”
I can successfully use my main account, but I need to add another one for an account I manage with a relative and that is the error I get. The 2nd account exists on eBay and works properly, so how do I fix this?
If you still get the same error today, this is what worked for another customer:
• Remove all accounts in the GarageSale preferences > Accounts. Quit GarageSale.
• Open the “Keychain Access” application. Remove all entries of kind “GarageSale eBay account” and “eBay token”.
• Restart your Mac.
• Open the GarageSale preferences > Accounts. Try to re-add your eBay accounts.
Before doing this you might want to create a new macOS user account, open GarageSale there and add your main eBay account in the GarageSale preferences > Account. Just as a backup.
