This video gives 4 reasons why the container control in Power Apps canvas apps is better than groups.
Container controls offer a powerful way to manage and store data in Power Apps. Unlike Group controls, Container controls can store larger amounts of data, making them ideal for storing images, videos, or other media. Containers are also easier to use when creating complex formulas, as they allow you to use multiple data sources in a single formula.
Additionally, Container controls can be used to store complex data such as multi-dimensional arrays, which can be difficult to store in Group controls. Overall, Container controls offer greater flexibility and power compared to Group controls, making them a better choice for more advanced Power Apps applications.
