Thats great!No need to worry. Dec 2 wasn't that long ago, just be patient. I was in process Sep 9 and only received biometrics today.
You finally got it after a long wait.
It takes really long time for some applications for DM while some cases get DM withing a week.
I think every case is different and as you said i will wait for the DM on sponsership app.
Thanks for your input
