What’s happening?
Customers are experiencing performance issues with Power Apps, specifically related to the use of the ForAll function when uploading records in a gallery within their canvas app. 
 

Reason:
The performance issues arise from the use of nested ForAll functions to collect and patch entries into the source table, which has resulted in significant slowdowns. 
 

Resolution:

  • For performance issues with the ForAll function:
    • Consider using delegable functions that offload processing to the cloud data source. Examples of such functions include Filter, Search, Sort, and LookUp.
    • Review the list of delegable functions for the data source being used to optimize the app's performance.
  • For further guidance on common canvas apps performance issues and resolutions, refer to the relevant documentation.
If further assistance is needed, consider reaching out to Microsoft Support for app development and optimization.
