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 they will 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 no network communication happens between PSPDFKit and end user devices. Simply renewing the license on our backend will not change anything about the behavior in your application, as we don’t have the ability to change how your apps behave in production.
