I’m developing an app with Adalo (Cardsy) and have a question about an issue reported by Apple App Review.
In the latest update (v48.0), I added one new icon on the Home screen that simply navigates to a new screen when tapped. No other logic changes were made.
However, Apple App Review reported the following issue:
Issue: App displays a blank screen after launch
Devices: iPhone 13 mini, iPad Air 11-inch (M2)
OS: iOS 26.2 / iPadOS 26.2
What’s confusing is that I cannot reproduce this issue in any of my environments:
Adalo Preview: no issue
Web App: no issue
Progressive App (iOS / Android): no issue
Tested with both new and existing users
Details of the added icon:
Image is from Adalo Media Library (not an external URL)
No database references
No conditional visibility
No custom actions
Simple navigation to another screen
Has anyone experienced a case where a blank screen occurs only on specific iOS devices / OS versions, but not in Preview, Web, or Progressive App?
Any ideas on possible causes or effective ways to isolate the issue would be greatly appreciated.
Have you changed anything in the first screen (welcome screen)? Any screenshots? Did Apple shared any screenshots? What are the components in the ‘Send 2’ screen? Have you tested through TestFlight first?
”Issue Description
The app exhibited one or more bugs that would negatively impact users.
Bug description: the app displayed a blank screen after launch.
Review device details:
Device type: iPhone 13 mini and iPad Air 11-inch (M2)
OS version: iOS 26.2 and iPadOS 26.2
Next Steps
Test the app on supported devices to identify and resolve bugs and stability issues before submitting for review.
If the bug cannot be reproduced, try the following:
For new apps, uninstall all previous versions of the app from a device, then install and follow the steps to reproduce.
For app updates, install the new version as an update to the previous version, then follow the steps to reproduce.”
I’ve seen this exact “blank screen after launch” rejection from Apple Review on specific devices, it’s almost always a native iOS render timing issue in the build, especially after adding new navigation or icons.
Even though it’s not reproducible in Preview/Web/PWA, Apple’s test environment (older/specific hardware like iPhone 13 mini or M2 iPad) can expose it.
Here are some proven steps that fixed this for several apps I’ve helped with:
Lighten the home screen and the new screen the icon links to: use native components only, no heavy custom lists, tight filtered collections if any (load minimal data on launch).
Remove any conditional visibility on the new icon or target screen containers (even simple ones can hide everything in certain builds).
Make sure that every screen doesn’t have so much links or connections to it.
Push a new TestFlight build (not update) and test there, it’s the closest to (Apple Review Environment).
If it’s clean in TestFlight, resubmit with notes explaining the timing tweak.
