Gallery Images not showing consistantly - mobile and tablet

[forcedLightning]

- Edit -

I've since clarified the issue, after some trial-and-error testing. When a device's cookies have been cleared, the images do not load until that browser has visited a SharePoint site (any site will do). If that browser has never visited SharePoint, the PowerApp will not load. Any way to fix this/pre-verify with SharePoint within the PowerApp?

Hello,

I have a product database app, and it pulls images from a SharePoint column, which contains the URL to a SharePoint Document Library containing the source image. The images show just fine on desktop, and sometimes on mobile and tablet. But after I cleared out cache and cookies on my tablet, they no longer show (they showed before). Also, they didn't show at all on my mobile device, and now they do show. So I'm confused.

Any thoughts on making sure images show on all platforms, or better ways to source images into a PowerApp? The only catch is they need to be associated with a particular SharePoint list item.

Thank you!

Hi @forcedLightning ，

This should be a loading problem.

You could suggest save the urls as a collection. Then use the value of the collection.

For example, set the app's OnStart: 

ClearCollect(data, listname)

PowerApps load collection will not cost much time. This is a kind of PowerApps internal data.

Best regards,
