When launching a whitelabel app from homescreen on Android, I do initially see a brief blank/white screen followed by the syncing/starting the app screen with progress bar, but only a gray background. Subsequent syncs show the custom sync background image.
I think the reason the initial progress bar screen doesn’t show the background is because the background image is defined in the app template, which is the thing being loaded or synced during that initial screen, in other words we have to load the template before we know what image to show on the load screen.
The initial white screen is the place where the AppSheet logo would usually appear. I thought the whitelabel process for iOS lets you replace it with your own logo, but I know on Android the AppSheet branding is just removed. I’m not sure whether there are technical limitations preventing us from showing a custom logo on Android, but even if it can be done I suspect it would not be a quick fix due to the complexity of the whitelabel process. @Brian_Sabino
