Thanks for posting the timelines, folks. Helps those of us that check status updates daily to feel better about no changes on the websites.
Recently received 100% P&T dated back to 8/2018. Filed for discharge on 7/17/19 via emailing them P&T letter, application, and even my decision letter (wasn't sure what to include and that was before I found this forum). Now I know I didn't need to send them the decision letter.
Received a couple letters it's all under review, status on website also shows "Application Under Review" still. Based on NervousNelly's timeline (submitted application May 14 I think and just recently discharged in August), if approved, I can expect discharge/refund around November or December.
