If so, yes can make changes, and you should be making changes. At a minimum you should be updating your flight times and other things like receiving a new medical.

LORs are not scored as part of the application, they just need to be in before the virtual interview takes place (and they were allow exceptions to this recently).
You are correct about referring to the the pilot credentials profile. Thanks for the advice!
