From what I’ve seen, if it was going to go to processing (manual route) then it will change to it a lot faster, usually within about a week of documents received (as long as they’re not waiting for anything else from you).
Pretty much all the other times I’ve seen people wait 1-2 weeks after documents received it’s gone straight to approved.
The change to “processing” doesn’t mean they’re actually processing it, it just means it’s been put on the pile to go to manual processing. Where as there’s no “gone to digital processing” update, you have to just wait for the approved so it might seem like it’s not moving.
I’d say currently the wait is 2-4 weeks digital and 8-10 manual depending on what they need from you and whether they transfer it internally.
