I’m in the same boat as you. I submitted June 14, and files were sent on the 19th.
I can actually see when they tested since I’m using Gamesparks and can track logins. The last time they tested was on the 20th, but I don’t know how that test went since we do not receive any communications.
They might be swamped with submissions, but if they found something wrong a month ago, it would be nice to know back then so I can fix it rather than just sit and wait for it to go through their entire process before hearing something is wrong.
