You always have the option to send an LOE using a web form after the application has been submitted, if you feel the need to clarify something. I personally have sent webforms in my own case. But if the lawyer says its fine then its probably going to be okay.We assumed since they could be edited they wouldn't have to be identical, nor that an LOE needed to be provided. Fuck ><.
The application was originally made in early/mid 2020, but my partner hadn't fully submitted it. We spoke to a lawyer in December and she said "just submit it, then open up a new application in your partners name too" - so the application had old information anyway.
