Given IRCC's 2022 budget forecast that they will be processing about 40,000 of the remaining (those not processed in 2021) TR to PR applications in 2022 and then the remaining 32,000 in 2023, this means there are now many people waiting for progress through this year. I think IRCC is trying to get as many people linked as possible to help cut down the number of inquiries about 'why can't I see or link my account' but that does not mean they will be able to completely process everyone in 2022.
Unless you know for sure that your application will be rejected (which it shouldn't be if you were eligible & provided all necessary documentation), or if you have some other urgent circumstance, I would save my money, be patient and not bog down the system with another application. Given your timeline and the fact that you started seeing progress in Jan and none since, I would request the GCMS notes to see if you can identify any issues that might be holding up your case, and then try to proactively address them through a Webform letter of explanation with or without supporting documents. This is what I will be doing if I don't hear anything further by the end of June.
