Greetings! @Krutik posted a question that I thought would make a good example video for custom app development.
I put together a video that walks through how to create the custom app, including the module configuration, as well as a custom IML function to handle the comparison.
The video is 18m long, but I wanted to show how to use the module, as well as how to build it.
Here’s a link to the video: Make (Integromat) Custom App Exercise Easy and "cheap" array comparisons with custom IML functions - YouTube
If you want the custom app and the blueprint, you can snag it here: Make Custom App – Create a simple difference array comparison app - ifOnly Solutions
