The forms for ticket ordering do not come up.

It takes about two minutes until they are loaded. This problem occurred recently after everything worked well for several weeks.

Can you please provide URL of your website so that we can inspect your code. Maybe you are using script block(source code) for embedding your form on website. We recommend using of iFrame code. You can try to replace source code with iFrame to see if the form will load faster. In this article you can find out how to do it.

Hope this will help.
