Subscription License Validation

Important: If you have shipped PSPDFKit 5.1.0 – 5.1.4 for iOS or 2.0.0 – 2.1.0 for Android, you should update to a newer version immediately. These versions have a bug where expired licenses will fail the license verification process and cause your app to exit unexpectedly.

Versions outside of this range will log if an expired subscription license is used, but continue to function as expected on actual devices. We strongly suggest updating as soon as possible.

We apologize for any inconvenience this may have caused.

How License Validation Works

License validation in PSPDFKit happens offline to ensure that no network communication happens between PSPDFKit and end user devices. (You can learn more in our PSPDFKit SDK Security article.) Simply renewing the license on our backend will not change anything about the behavior in your application. We don't have the ability to change how your apps behave in production.

Workarounds

Date

As a temporary workaround, you can change the date on the iOS device — setting it back a few months should be sufficient, and this will hopefully reenable working with the app until you've pushed a fix that correctly addresses this issue.

App Store

If your app is in the App Store and issues related to PSPDFKit 5.1.0. are causing problems, we recommend asking for an Expedited App Review, which is usually processed in less than a day.
