There could be several reasons why your PowerApps application is experiencing slow loading times and unresponsiveness. Here are some common issues and potential solutions:
Large Datasets: If your app is loading large sets of data, it can slow down performance. Try to load only the data you need immediately and paginate or cache the rest.
Too Many Columns: Retrieving too many columns from your data source can increase network overhead and memory usage. Select only the necessary columns for your app.
Unsupported or Legacy Browsers: Ensure you are using modern, updated, and supported browsers. Older browsers may not handle the app efficiently.
Geographical Distance: The performance might vary based on the geographical location of your data source and users. Try to place the data source closer to the majority of your users.
Server-Side Issues: Poor performance might be caused by server-side issues such as missing indexes, large data joins, or resource contention. Use monitoring tools to assess and address these issues.
Preload App Setting: Enable the "Preload app for enhanced performance" setting in PowerApps. This can help improve the loading time of your app.
