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.

1
Access your account plans

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).

2
Manage active devices

Click on 'Manage Plans' and scroll to the bottom of the page to locate the list of devices currently signed in with your subscription.

3
Deactivate old devices

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.

4
Restart the mobile app

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.

5
Test the combine feature

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.
