Walkaround to solve the cache issues when switching between Edit/New and View forms

i have always had this issue where PowerApps SharePoint integrated forms shows the previous loaded form very briefly before navigating and showing the correct data. i have looked everywhere for solutions and not found any. Not sure if Microsoft are looking at fixing in the future, i'm just looking for any walk-around. My users are loosing trust mainly because they are having to see old data briefly. 

i'm looking for a solution that would show a blank screen briefly instead before navigating to the actual form that was clicked by the user.

Since PowerApps always caches the last form/data that was visited, i was wandering if it is possible to make a blank screen the last cached data, so that when a user clicks the new form button or view form button the blank screen shows first before the actual form displays.

 

Now the challenge i have is how to tackle the OnCancel scenario.  This is tricky because there are about 3 different ways to cancel a form(the Cancel button, the 'x' at the top right, clicking outside the form). 
i can navigate to the blank screen using the OnCancel property. i just don't know how to handle the other scenarios where the user clicks on the 'x' button or clicks outside the form.

This is how far I've gone

OnCancel-
If(SharePointFormMode="CreateForm", ResetForm(FormNew);Navigate(BlankScreen,ScreenTransition.None), ResetForm(FormEdit);Navigate(BlankScreen,ScreenTransition.None))

OnNew-
Set(SharePointFormMode, "CreateForm");ResetForm(FormNew);NewForm(FormNew);Navigate(FormScreenNew,ScreenTransition.None)
OnEdit-
Set(SharePointFormMode, "EditForm");EditForm(FormEdit);Navigate(FormScreenEdit,ScreenTransition.Cover)

OnView-
Set(SharePointFormMode, "ShowForm");ViewForm(FormEdit);Navigate(FormScreenEdit,ScreenTransition.Fade)

OnSave-
If(SharePointFormMode="CreateForm", SubmitForm(FormNew);Navigate(BlankScreen), SubmitForm(FormEdit);Navigate(BlankScreen))

Re: Walkaround to solve the cache issues when switching between Edit/New and View forms

Hi @Gottijay2000 ,

Here is something I use when galleries have to refresh to stop the user thinking the screen is frozen and start clicking things.

Do a new blank screen with the background RGBA( 230, 230, 230, 0.5) and put the spinner (attached) in the middle.

Right at the start of your code Navigate to this screen with Transition.Fade and then back again to your screen at the end of the code with the same transition.

Screen fades to spinner and then fades in again at code end. I am wondering if this would hide the experience you are having.
