Fix Missing Adobe Acrobat Menu and Signature Options on iPhone
Question details
The user cannot find the standard menu bar or saved signature options in the mobile PDF app, leaving only basic PDF editing tools available.

- Product
- Adobe Acrobat
- Device & OS
- iPhone (iOS)
- Scenario
- Opening a PDF file to fill and sign after a recent app update or iOS system update.
- Observed behavior
- The top menu bar and the 'Fill & Sign' signature options unexpectedly disappear from the user interface.
Ensure you have a stable internet connection and know your Adobe ID credentials, as you may need to sign back in or restore purchases to reactivate your tools.
Restore Premium Purchases and Re-login
Often, premium features like advanced signing disappear because the app has logged you out or temporarily lost your subscription status after a software update.
If you rely on premium editing tools, a simple session refresh will usually force the app to recognize your subscription and display the hidden menus.
Open Adobe Acrobat on your iPhone, tap on your Profile icon in the top corner, and ensure you are signed into the Adobe account associated with your Premium subscription.
Navigate to the app Settings, tap on 'Subscriptions', and select 'Restore Purchases' to force the app to retrieve your active plan.
Force close the Acrobat app by swiping it away from your recent apps list, then reopen it.
Open your PDF file again and tap the action menu to see if the 'Fill & Sign' or signature tools have reappeared.

Update or Reinstall the Acrobat App
Outdated application versions or corrupted cache files from an iOS update can cause UI elements like menus to vanish.

Frequently Asked Questions
Why did my saved signatures disappear after an iOS update?
Major iOS updates can sometimes reset application permissions or clear the temporary app cache where local signatures are stored. Recreating the signature once usually resolves the issue permanently.
Where is the Fill & Sign tool located in the new Acrobat update?
Adobe frequently modernizes its mobile UI. If it is no longer in the top menu bar, the Fill & Sign tool is usually found by tapping the blue '+' action button or navigating to the 'Tools' tab at the bottom of the screen.
Do I need a premium subscription to sign PDFs on my iPhone?
While basic PDF viewing is free in Acrobat, some advanced form filling or unlimited signing capabilities require a premium subscription. Alternatively, comprehensive apps like WPS Office offer excellent free basic PDF signing features for mobile.
