Konstantin 🎉be aware that you guys made a breaking change... so there are multiple implementations that are broken now e.g: https://github.com/firefly-iii/firefly-iii/issues/1857 and some personal projects of some devs that have also poked me.
Would appreciate if this can be fixed sooner rather then later. And of crouse, please try not to make breaking changes without any heads up. Imagine MasterCard making a breaking change in their API and not update their SDK's... on a Friday night.... at 1700 :).
