Verified issue does not already exist?

• I have searched and found no existing issue
• I will be providing steps how to reproduce the bug (in most cases this will also mean uploading a demo budget file)

What happened?

I tried to add bank account from MBANK_RETAIL_BREXPLPW but every time I get "An error occurred while linking your account, sorry!"

Steps to reproduce:

Looking at the backend logs, there is a problem with request to /api/v2/agreements/enduser/, which always return 400 Bad Request.
I can add accounts from other institutions without any problems.
I'm using the latest version of Actual, v24.7.0

What browsers are you seeing the problem on?

Chrome

Operating System

Windows 11

Perfect. The community will be able to assist better on Discord with debugging this issue. If they deem it to be a real bug in actual (and not in GoCardless or SimpleFin which it usually is) - then we can open up an issue.

Why this way? Because we have a lot of people actively assisting with tech support on Discord. Whereas on github we mostly have the maintainers who are very limited in their capacity to offer tech support.
