How do you know your letters of recommendations have been sent out as part of your application? Have you received an e-mail about LOR specifically or did you see the status change from received to sent?
My LOR's went out seperately from my application. Once they were sent their status changed on Infosource from "received" to "sent". You can also contact AADSAS directly via phone to determine if/when/which LORs were sent out.
