Install the Correct App and Verify Your Account Sign-In

Upgrade prompts usually appear when you are signed out, using a secondary free account, or attempting to open the PDF in a third-party basic viewer rather than the official app.

To utilize premium features like advanced form filling and seamless sharing, the official app must actively sync your subscription status from the server. Re-authenticating your account often resolves false upgrade prompts.

1
Download or Update the App

Go to your device's app store (Google Play Store or Apple App Store) and ensure you have the latest version of Adobe Acrobat Reader Mobile installed.

2
Sign In to Your Account

Launch the app, tap the profile or settings icon in the top corner, and select 'Sign In'. Enter the credentials tied to your active premium subscription.

3
Fill the PDF Form

Open your target PDF document. Tap the 'Fill & Sign' tool (usually represented by a pencil icon) from the bottom action menu to begin typing into the form fields.

4
Share via Email

Once you have finished filling out the form, tap the 'Share' icon at the top of the screen. Select 'Send a Copy' to generate a file attachment and choose your email client to send it.

Install the Correct App and Verify Your Account Sign-In
Check Subscription Status: If the upgrade prompt continues to appear after signing in, log into your account via a web browser on a computer to confirm that your subscription is fully active and payment has not failed.

Frequently Asked Questions

Why am I being asked to upgrade when I already have a subscription?

This occurs when the app fails to recognize your active subscription. It usually happens if you are signed out, using the wrong email address, or if the app's cache needs to be cleared to force a synchronization with the server.

How do I email a completed PDF form directly from my phone?

After saving your filled data, look for a 'Share' or 'Export' button in your PDF reader. Select 'Send a Copy' or 'Share File', which will prompt your phone's share sheet. From there, select your email app to automatically attach the PDF to a new message.

Why are the text fields in my PDF not selectable or typable?

If you cannot click into a field, the PDF might be a flattened image rather than an interactive form, or it may have security restrictions. To fill a flat PDF, use a 'Fill & Sign' feature to manually insert custom text boxes over the blank lines.

Can I fill out online PDF forms without downloading an app?

While some mobile browsers can display PDFs, most lack the capability to edit or save form data. For a reliable experience where your inputted text actually saves, using a dedicated app like WPS Office is highly recommended.
