Hello,
Thank you for reaching out to us.
To assist you more effectively, we kindly request that you record a video demonstrating the issue and the steps leading to it. This will help us better understand and replicate the problem on our end.
Upload the video on a filesharing service, for example – https://wetransfer.com/ , and provide us with the URL.
We understand the urgency of the issue you are experiencing with the checkout process on your website.
Please note that none of our other clients have reported this problem, and the last theme update was not released recently. Therefore, it is likely that there may be another cause for the issue you are encountering.
Could you please confirm whether you are using any third-party payment plugins? If so, does the checkout process work correctly when those plugins are disabled?
Additionally, have you made any custom modifications to the theme files?
Warm Regards,
The 8Theme Team
