Both errors are under the same investigation number, Lady FD.
As I've checked, our engineers are still working with the affected banks to resolve the issue when adding or reconnecting accounts.
In the meantime, you have the option to temporarily import your banking transactions using a CSV file. Check out this article if you want to try out this option: Import Bank Transactions Using Excel CSV Files.
Please take note that these transactions will be part of the automatic download once the connection is working again. These means that you'll need to exclude them to avoid duplicate banking transactions in your account.
We'll post and share the update in this thread as soon as we receive them from our engineering team. Let me know if you need anything else so I can get back here and offer my help again.
