- iOS
- Scenario
- Attempting to fill out or interact with interactive form elements on an iPhone or iPad after installing the latest iOS system update.
- Observed behavior
- The button boxes in the forms fail to register taps or function properly, causing significant disruptions to business operations and data entry workflows.
Before proceeding with troubleshooting steps, back up your form documents to a cloud service to prevent data loss during app reinstallations.
Restart Your iOS Device and Reinstall the Application
Performing a clean device restart and reinstalling the app ensures you clear temporary caches and install the latest compatibility patches from the developer.
Major system updates can occasionally disrupt how applications render interactive UI elements. A fresh installation typically forces the app to realign with the new iOS framework.
Press and hold the volume down button and the side power button simultaneously. When the power-off slider appears, drag it to turn off the device. Wait one minute, then turn the device back on.
Locate the affected form or office application on your home screen. Long-press the app icon, tap 'Remove App', and confirm that you want to delete it from your device.
Open the App Store, search for your application, and tap the download icon to reinstall it. Launch the app to see if the button box facility has been restored.

Modify the Document with Alternative Form Fields
If the issue is pending a developer patch, editing the source document to use alternative form controls can serve as a highly effective temporary workaround.

Frequently Asked Questions
Why do form controls like button boxes break after updating iOS?
System updates often alter core rendering engines or UI frameworks. If an application is not fully optimized for these changes, complex interactive elements like button boxes may temporarily lose their functionality until the app developer releases a compatibility patch.
Will I lose my existing form data if I reinstall the application?
Yes, if your forms are saved exclusively within the app's local storage directory, they may be deleted during uninstallation. Always back up your critical documents to a cloud service like WPS Cloud, iCloud, or Google Drive before removing the app.
Are there other ways to open a form if the button box is currently broken on my app?
Yes, you can try opening the form document using a different mobile office suite such as WPS Office for iOS, or transfer the file to a desktop computer where the form controls remain unaffected by mobile operating system updates.
