Cannot Unisolate a device through defender API

Question

This action is about the defender API - Unisolate device. We can sucesfully use defender API to isolate a device but unisolation in the same way doesn't work.
We always get the same message "Cannot unisolate a device that is unisolated".

If we go to security.microsoft.com and lookup the device, then the device is isolated and we can unisolate the device through the webbrowser but api doesn't work.
