I'm aware that the test currently fails.
The underlying API's had to be changed in order to keep working.
I've had time to rework the code but not the tests.
Since now another API is used the test suite for this provider must be rewritten completely.

Edit:
The change is recent and since I noticed users where having issues I put the code into this PR so that they could be referred to it. I'm fully aware of the work that must be completed before being mergeable again.
