----------
We are aware of an issue with American Funds (Retirement Planning) accounts not syncing or linking. Our aggregation team is aware of the issue and is investigating the cause. As soon as we have a resolution for this we will update this space.
If you have synced accounts, please do not delete them as this would permanently remove the historical data. Leave the linked accounts or setup for American Funds (Retirement Planning) in the current error state and we will provide further information as it becomes available.
Thank you for your patience while we work on this issue!
