Hello, @Goostaf,
Thank you for providing us with access to the wp-admin panel.
We have temporarily activated the XStore parent theme on your website and found that the Wishlist page functions correctly on mobile devices without any issues. This confirms that the problem is caused by custom code modifications within your child theme.
To resolve this issue, we kindly recommend reviewing the additional code customizations in your child theme and consulting your website developer to address and fix the problem.
We hope this information is helpful. Should you have any further questions or require additional assistance, please do not hesitate to reach out.
Best regards,
The 8Theme Team
