Refreshing of screen is very slow

[Anonymous]

When the user opens an application the load up of data on the screen is very disjointed and very slow.  The response time between typing and appearing on the screen is very slow between 3-4 second delay before the writing appears on the screen.

This is being experienced on an iPad

Version iOS 11.4.1

PowerApps version 3.18083.30

I have a video to show the experience however, it is having issues attaching to this ticket.

Hi @Anonymous,

What is your data source and how many records are there? Check in your app and see if there is any delegation warnings about the formulas.

About delegation:

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/delegation-overview

If the data in your data source exceeds 500 records and a function can't be delegated, PowerApps might not be able to retrieve all of the data, and your app may have wrong results. Delegation warnings help you manage your app so that it has correct results.

Regards,

Mona
