Your lawyer does not sound like they know what they're talking about or just want to avoid extra work.
In our application we had more red flags than probably more than 95% of the applications here - applying through outland process while out of status in Canada and without even being married - applying under common law after living together for just a year.
Did not have a lawyer (maybe having a lawyer is a red flag
).
Requested notes 3 times and it does not look like it affected anything negatively, if anything it might've sped up things as application was processed in under 10 months. Did not have an interview either.
