App looses track when replying to long thread emails with 1 recipient. Randomly picks a previous email making it impossible for me to appropriately reply to last email. When I forward a 3rd party email in this thread, it keeps that forwarded email at the top of the thread. App has also added the email address of that 3rd party to receive my next reply. Had I not caught it prior to sending, conversation with my attorney would have been forwarded to 3rd party. Many drafts stuck in thread. Annoyed.
