Problem: If you're experiencing issues with the missing Save button in the Advanced Translation Editor (ATE) on a multisite installation while using DeepL and Gutenberg, and have noticed that new translations are not saving properly, requiring repeated translations of the same paragraphs, this might be similar to your situation. Solution: We have replaced the Save button with a new auto-save feature that activates automatically after a few seconds. This change was implemented to enhance the user experience by reducing the need for manual saves. For more details on this update, please refer to our forum post: WPML forum post about the auto-save feature.
If this solution does not relate to your issue, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Additionally, if you need further assistance, please open a new support ticket at WPML support forum.
