Where do i see how much of the import job is finished?

It says wait you can’t start the import until the exisitng import is finished.
How long wil it take to finish and
How do i stop it ?

Right now it’s not possible but we plan to add this functionality: How do i stop the database duplication or import process? - #2 by olgatrykush

Imports have a maximum runtime of 30 minutes, after which they are automatically canceled. If this happens, you need to wait and then start a new import.
