I have received my PR result after 6 months.
Here is my info:
Age: 25
Gender: Male
Marriage status: Single
Job: System Analyst
Nationality: Malaysian
Race: Chinese
Religion: Buddhism
Salary: - Average as what you find online, I cant post it here as I am using personal account.
Original Pass: EP with 2 years
Timeline:
21 May 2019 - Started working in SG
08 Jan 2020 - Apply for ePR, after 6 payslips as per requirement. (before increment and paying taxes)
26 July 2020 (Sunday morning) - ePR Status changed to approved! Approved date stated as 13 July 2020. (I refresh every few hours so I know the exact date when it is updated, lol)
Something I've noticed is that in 'https://eservices.ica.gov.sg/ipepr/index.xhtml', before 13 July (approval), it is showing me a dropdown to 'Submit requested documents':

After 13 July, the dropdown is gone:

After checking online and with my friends, I found that the processing time is very random.
One of my friend got it after 3 months, studied in MY, staying in SG for 2 years +.
One of them got it after 4 months, studied in SG, and working for 2 years+, got it right before Covid period.
And other are 6 months to 1 years +. (and some stayed for many many years and still getting rejected)
So... Luck is the key here..
Hope you guys got yours soon!
