thank you. I could switch back.

Hi Yves Kurz we're working on this feature and it will be available in the next few weeks. In the short term, could you switch back to the old console to upload a .backup or .dump file? You can do this by clicking on your name in the top right menu, and then 'Switch to classic experience'. Let me know if that works for you.

.. and i cannot switch back to old console :(
