Fix Incorrect PDF File Order When Combining Documents in Acrobat Mobile
Question details
The user is experiencing an issue where PDF files appear in the wrong order after being combined using the mobile app.

- Product
- Adobe Acrobat Mobile
- Device & OS
- Android
- Scenario
- Combining multiple PDF documents into a single file on a mobile device.
- Observed behavior
- The pages of the combined PDF are placed out of order, likely due to account synchronization conflicts caused by multiple active device sign-ins.
Ensure you have access to a desktop computer and your account login credentials, as managing account device activations is most effectively done via a web browser.
Deactivate Unused Devices to Fix Synchronization Issues
Resolve account syncing conflicts that disrupt PDF file combining by removing inactive devices from your subscription plan.
Although a single ID can be used across multiple devices, being signed in simultaneously on too many devices can cause the mobile app to fail when synchronizing tasks like combining files. Managing your plan from a desktop computer clears these synchronization blockers.
Open a web browser on a desktop computer and navigate to the official account management page for your subscription (e.g., account.adobe.com/plans).
Click on 'Manage Plans' and scroll to the bottom of the page to locate the list of devices currently signed in with your subscription.
Remove or deactivate any computers or mobile devices that you are no longer using. Ensure that only the device you are currently troubleshooting remains active.
On your Android device, sign out of the mobile app completely. Close the application, open it again, and sign back in to refresh your synchronization status.
Select the PDF files you want to merge and test the combine function again to verify that they are now processing in the correct order.

Frequently Asked Questions
Why does my mobile app change the order of PDFs when combining them?
This is often caused by a background synchronization error. When your account is active on too many devices, the cloud server may struggle to process the exact sequence of your files, leading to an incorrect output.
Can I fix this issue directly from my Android phone?
While you can sign out and back in on your phone, managing and deactivating other devices tied to your subscription plan is usually required, which is much easier to navigate using a desktop web browser.
How many devices can I stay signed into at once?
Most premium document subscription plans limit simultaneous active sign-ins to two devices (for example, one desktop and one mobile device). Exceeding this limit commonly triggers sync and processing errors.
