Hi Olive, Thanks for your reply! Oddly enough it is working for me now on all the links you provided here. If I remember correctly, there was some CORS error in the log, which I did not include in my first post. Maybe there was some config issue on the backend/3rd-party?
Anyways, thanks for replying to my post and sorry for calling the project abandoned - in my quick search I did not find too much recent activity and maybe I am a bit of a burnt child in that way :S
