There's nothing to worry about for most people here in the January thread. Think about how many applications flooded the system in October and November... A backlog was almost certain to occur when it comes time for them to start scheduling tests and oaths, since there are only so many slots available. It's a nice dream to think that processing was going to take a similar amount of time as it historically has, but this is a different situation now. And through this whole time IRCC still estimates that 12 months is the processing time.
Personally I think the wait times between each stage will continue to creep longer and longer while those who applied last year are cleared through to make space for our turns. It doesn't mean there's anything wrong. It just means they're not ready for you yet.
I think for a lot of us here were so traumatized by the fear of the unknown while waiting for our PR, that we've forgotten what the P stands for.
