Yes it could be but right the delay doesn't seem to be because of that. There are many people who have no travel history, work documents as per IRCC norms and duly acknowledged in GCMS Notes by Case Analysts, only one home country PCC, people working in Canada since last few years on work permit etc.
To me it looks like transitional losses between agents especially when files are moved from one VO to another (in particular for workload redistribution).
Having said that, there is nothing one can do to expedite the process but can try to occasionally drop reminder by way of calls, CSE, Mail etc, keep up the patience and hope.
True i second that it also depends on luck , sometimes your file might end up with an Officer who works fast and updates everything accordingly . where as some Officers will not update the online status neither will try to finish the work soon ( can be various reasons )
Calling them or raising a webform looks like a good way to keep them reminding about your application but i doubt the case will move forward if we do this ( i may be wrong ) .
my AOR is june 1 and medicals passed 12 june 2018 and i have not see a single update in my profile until 18th jan 2019 ( i have not contacted them regarding my case )
