Hi Quicken Kristina,
Just need to add the following in this thread: I'm on Quicken Premier (R68.38), encountered this exact issue when attempting to link Synchrony Amazon & TJX accounts to Quicken on Thursday (7/16/2026) as previously stated, no matter how many times we input the correct Synchrony credentials, (including Deactivating/Reactivating) the system would not accept the credentials and repeatedly returned error CC-503. With the OSU not functioning for Amazon, we were also unable to activate the new Retail Purchase Categorization tool - !!
The point of posting this is to request that Quicken Premier Support be be brought up to speed and be cognizant of this unresolved issue to avoid unnecessary time troubleshooting this error with other Quicken customers. Since the Support specialist was unaware of the unresolved matter (made no mention of this on the support call), we repeatedly attempted to rectify the connection only to fail each time. At the end of the Support call, the technician surmised the error was the result of too many attempts to connect to Synchrony Amazon and would be resolved within 24 hours (due to excessive login attempts). Kindly escalate this matter to Quicken Support as soon as possible.
Thanks in advance for your assistance.
