Frequently Asked Questions

Why are my PDF editing tools suddenly missing on my iPhone?

Tools can disappear due to an outdated app version, a synchronization glitch with your premium subscription, or because the specific PDF document you opened has restricted editing permissions set by the author.

Does a password-protected PDF hide the Edit and Sign tools?

Yes. If a PDF is secured with an owner password that explicitly restricts modifications or form filling, mobile PDF applications will typically hide or gray out the 'Edit PDF' and 'Fill & Sign' tools to enforce the document's security.

How can I check if my premium document subscription is active on my iPhone?

Open your iPhone's 'Settings' app, tap your Apple ID name at the top, select 'Subscriptions', and look for your premium PDF app subscription under the 'Active' list. If you subscribed directly through the provider's website, you may need to check your account status on their official web portal.
