I haven't heard anything either. My payment was confirmed on 8/2/15. The website says that your supp. app won't be processed until 4-6 weeks after you submitted it, and that when it is processed you will receive the "Application Complete" email. I'm thinking that in July they were less busy, but now they have a LOT of apps to sort through and it's taking them much longer to process everything. If you haven't heard anything and it has been less than 4-6 weeks, just sit tight. It will be our time before we know it!
Also note that in last year's thread, batches 5-7ish weren't processed/reviewed until October. Unfortunately.
