@David *******
I think there you have a good point. Just provide what they ask, not more.
When they need more, they will ask for it.
I myself only sent bank statement just from the date I applied and employment contract.
Then they asked for a letter of my employer stating I could work remotely.
After that it was approved within a day.
People here read what was asked and start to provide more and more at initial application, and hope they get no additional questions, but that indeed might be a red flag to the officer, because it does show you are not confident you comply with requirements.
