Finally! Many cards, as listed in the title, are difficult to set up since Synchrony did not have accounts set up using their universal account manager login. I periodically check, and finally, you can set up all these cards if you use the add account option for "Synchrony Financial Mastercard". I have already converted my Walmart OnePay and JCPenney cards using this method. Previously, I had to access my OnePay card by logging on to a Lowe's Synchrony account. But no more!
