Power Apps Review, Troubleshooting, and Optimization

Do you want to learn how to go through an existing Power Apps app and make it better? Then check out this video. We take my app that started 10 years ago and break it down. You will learn how to work through an unknown app, how to troubleshoot it, and how to make it better. Kind of fun revisiting an old app and discussing how I would have done it better.

Yes, the video is really long but that is what it took to really go through an app piece by piece to understand it and talk about how to get it to today's standards!
