Partnership work visa for my partner has been approved!

[skadsuh]

Timeline:

January 22, 2019 - submitted application with evidence online
January 25, 2019 - We received an email stating that the application has been approved in the letter and was given a new expiry date.

The approval was so fast I still can't believe it.

Just a couple of question:
1. We have not had an immigration officer. We just received a letter of approval. Is this normal for immigration now?
2. How can we have a physical label if not a single immigration officer contacted us regarding our application?
3. In applying work, usually they scan the visa label on the passport. How can we use the e-visa for this? Im just a little confuse.

For everyone who have helped us, Thank you very much.
