Planning Center import window is empty (I dont know where to login)

Hi, i tried today to import a schedule from Planning Center. It was the first time.
But in Quelea the Planning Center Window was just empty.
Where can I login to Planning Center?

I hope someone could help me.

Are you using the latest version of Quelea? This was broken previously but should be fixed in 2020.0.

Yes I use 2020.0
it is not a big problem for me, I continue to do the processes manually. It’s a cool feature that I wanted to test.
Here is a picture of the Planning Center login window I see in Quelea.

I will try the actual CI Version too maybe it will work.!

I tested the actual 2021 CI Version. There is the same Problem
