We've a game that the first version has published 45 days again with a quick review and direct approve.
After that initial version, we've made some big updates and additions as well as some bug fixes to get ready to officially publish our game, and market it. However, with my first update, it waited in the review queue for 2 weeks, which I then cancelled, make some bug fixes, and sent to review again since I heard that this can fix the process sometimes.
Even after that, we've been waiting for 3 weeks and still no updates. I've also applied for Expedited Review since this is getting urgent after waiting more than a month. I hope someone from Apple Support team will see this and help me with the issue.
