I will advice to ignore the 20 months processing time, I just got portal 1 on September 30th after Aip in May 2023. So it took them 16 months to send me portal 1 after AIP. So just relax and be checking your mail regularly.
Reconsideration goes back to the officer and he will decide either to reopen the case and view again or not but federal goes to the court for re determination. I hope this help.
If the either of the decision is positive, you will proceed to the next level where you will be told to go and pay for your PR processing fee if you haven't paid for it earlier and submit a request documents that will come with the decision.
Anytime from 6 months upward you should be expecting a decision on either of the both. PRRA or H&C. Just keep praying for good decision. i wish you good luck.
