I had the same, waited even longer. It never got passed step 2 of 3. Tried to drag and drop, as well as upload the file. Only 200 contacts to merge. I also wanted to add them to a specific group of contacts, is there an option for that? Please let me know.
Hello @JeanM9. I'm sorry that you were having trouble uploading your contacts. When uploading a file of contacts, you can select an existing list or create a new list to add your contacts to. Were you able to upload your contacts since posting here? Were you seeing any messages when uploading the file? Please let us know if you still need assistance.
