Applied for
#10 earlier today. My 9-digit code "expiring" 10/15 worked fine. App still needs secondary review but I expect it to go thru as usual. (had to wait an extra month to get back under 6/6, due to annoying HP from AT&T cellular)
App ID was 20171204xxx which is the same format I've always seen going back years.
edit: got the approval email
