What happened?

When calculating the Starting Balance, the oldest transaction is taken as the last element of the list on the frontend:

But when using the simplefin integration, the sorting is not applied and the original sorting from their API is used, making the sorting newest -> oldest. This causes the frontend to create a starting balance dated to the youngest transaction, instead of the oldest as it should.

This can be reproduced quite quickly using the simplefin demo token:

For goCardless, I could find some sorting, and this code could be used to also sort simpleFin transactions:
