Hello, Bas Kling,
We regret to inform you that the issue you are experiencing is not related to the XStore theme. Like you, we are awaiting a resolution from WordPress.
In the meantime, we recommend trying our new Single Product Builder, which is based on Elementor and includes multiple templates. For more information and to access this feature, please review the attached files.
Thank you for your understanding and patience.
Best Regards,
8Theme’s Team
