USCIS finally published some statistics and numbers about affirmative asylum after 9 months. This data sheet is for 2019 fiscal year (Oct 2018 - Sep 2019). There are some interesting trends here that explain why a lot of people on the forum haven't got any receipt notices from USCIS even after 2-3 months.

1) The number of scheduled interviews by all offices has dropped down to 30-50% of what it used to be before Aug-Sep 2019. This means you will have to wait 2-3 times more than how long it usually took in early 2019 in order to get an interview. I'd say, three months after a filing I-589 is a reasonable guess. So, don't be surprised if you have to wait that long.
2) If you applied in August 2019, you have a tough luck getting an interview soon. Unfortunately, they started this new unwritten policy in August. So, if you a applied in August, there is a more than 50% chance that no interview was scheduled for you in that month and since you are in lowere priority than those who applied later than you, let's say in September or October, you're less likely to get an interview as long as the backlog in front of you hasn't become cleared yet. This is simple because of the LIFO policy that was implemented in 2018.
3) While they are conducting way fewer interviews now, they have, on the other hand, increased the number of cases that they adjudicate. For example, Chicago office went from deciding 552 cases in January 2019 up to 1246 cases in Sep 2019. Other offices show a similar pattern. This means that the current policy is to clear the backlog a little bit and give out more decisions.
4) A very noticeable reduction is observed in the number of asylum seekers from Latin America, Venezuela in particular. It must be because of recent regulations passed by Trump administration such as safe third country rule passed in Sep 2019 and EAD ineligibility rule for illegal presence and failure to appear at court and interview. As a direct result of that, you see far fewer number of applications have been received by Miami and other offices in the south in Sep 2019.
