Yes, I have read a similar write-up before that the IP1/NA2 stuffs don't make any sense now since IRCC has moved to a new workflow. But its true that the average processing time has increased drastically from the 3-4 months to 5- 7 months in the past months. Unfortunately these are not in our hands to change and all we have to do is to Wait, Wait and Wait patiently.I have read something over net. Sharing the link below:

It helped me to understand why the status doesn't get change. Hope it will be helpful for you as well.
