Before performing an update, you must test whether the update is possible. It is your responsibility to ensure that the third-party product is compatible with your platform, so proper testing should be conducted beforehand.

Also a third-party provider cannot predict how UNA Core will evolve, as no one can foresee future changes made by others. Therefore, updates will not always be automatically compatible. It is highly recommended to disable automatic updates and perform thorough testing on a staging site before applying any updates to your live platform.

If a third-party product is not compatible, you should contact the provider to request a paid or a free update. If the provider is no longer available, you may need to find an alternative provider in order to help you with the upgrade. Ultimately, these actions are your responsibility.

You cannot blame the UNA CMS creators for your actions/business dealings with third-party providers.
