I am a January applicant. Application delivered Jan 4, 2021 but got acknowledged by IRCC on Feb 13.... then got Medical and Biometrics request both on May 6... got my eligibility letter to sponsor May 7... my spouse did biometrics May 13 and medicals June 1. He passed medicals June 4... then July 13 he received pre arrival and E-CAS updated to decision made ... I finally linked the application to my profile July 16 after changing 1 applicant to 2 like you mentioned (you were right!) and then July 23, 2021 he got PPR ... now passport has been submitted to VFS Lagos so awaiting whenever it is ready for pick up. We had to courier the passport to them cos you take it there in person.
Don't worry, you will get PPR soon. I guess they are faster now because they are not processing other types of visas and focused primarily on family sponsorship.
