Tomorrow is our launch day - what is most important on launch day?

I'm sure you all know. As a founder, you eagerly await this one day. The launch of the product. Unfortunately, things often turn out differently than planned. We waited a long time for verification from Slack and our launch was delayed. But tomorrow is the day and we are going live with our coffee break app. After all this time, the launch should be successful. Are there any topics that are particularly important on launch day? Was your support team very busy on launch day? I'm really looking forward to your feedback and thank you for your support. The app is free for up to 25 users. You can find the launch link here: https://www.producthunt.com/prod... Good luck to everyone else who is launching this week!
