Hello All,

We are facing issue of app slowness even after using the 5G network.

We are using 5.0 release build

Here is the videos and screenshots:

We are not able to figure out why this is happening.

@nidhikachhawa24 The behaviour different in different devices but issue is with webview only on android devices

[nidhikachhawa24]

@HarishGangula

Yes.
For webview are we using any chrome plugin?
Had a call with Swayangjit, he did mentioned that the issue might be with chrome version.

[HarishGangula]

@nidhikachhawa24 We are not using any chrome plugin for it, whatever come with android which is webview it will use

Is there something that can possilby come in as a community contribution to get to a solution? Is there an active contributor who would be willing to take this issue on?

[HarishGangula]

@rhwarrier This is common issue across the ionic app ecosystem which need to be solved by them

@nidhikachhawa24 @HarishGangula
Long scrollable views with numerous box-shadow effects and CSS styles can significantly impact performance. To improve app responsiveness, remove all box-shadow properties from app.scss, themable.scss, and global.scss.

[HarishGangula]

Thanks for the info @Ajoymaity we will try this

[HarishGangula]

@Ajoymaity There is no improvements on performance after this change, It is due to rendering of assets which are images, JS and fonts on navigation between screens
