Hello,
Thank you for testing and for the detailed feedback.
Yes, since the behavior is the same with a default WordPress theme, it does not appear to be theme-related. An 18-second checkout is significantly better than before, though it can still be influenced by factors such as server performance.
If the issue becomes worse again, I’d recommend continuing to work with your hosting provider to review server logs and performance during checkout.
Feel free to reach out if you need anything else—we’re happy to help.
Thanks for contacting us.
Have a great day.
