I think there are 2 columns, one for the sponsor and one for the applicant.Mine is still shown as:
- We received your application for permanent residence on February 2, 2021.
under the sponsor one, it probably shows that it has started processing, but under the applicant one, it just shows that application has been received.
my guess is that they will check eligibilty of the sponsor first, and only after confirming that the sponsor is eligible to sponsor, they would start to look at the applicant Hence, the discrepency between the 2 different status under the sponsor and the applicant
