So I did a little analysis on myimmitracker. Criteria: AoR 2018, Jan to until now, received PPR and single applicant.
Found 167 cases. The longest time is 197 days

, while the lowest in only 16 days but these two are extreme cases. Many of the single applicants had to wait from 110 to 150 days. So, I am guessing that probably will be the expected timeline. If sooner, awesome. If not, patience, you got nothing else to do but wait anyway.
