Problem: The client is experiencing issues with the integration between WPML and Crowdin on a WordPress site supporting 20+ languages. The integration picks up unnecessary strings, and syncing between the two systems is unreliable, making it difficult to understand why updates are not reflected. Solution: We cannot provide a custom integration between WPML's automatic translation and Crowdin Translation Service as the translation memory systems of the two are incompatible. However, if you're facing issues with the current integration with Crowdin and need further investigation into what is not working, we are ready to assist you. Additionally, if you are considering moving to WPML's automatic translation option, please provide more details on what you aim to achieve and share your site's Debug information with us. You can find instructions on how to provide this information here.
