When using the Submit button, my forms are submitting the data, however, from the user side, nothing appears to be happening. No form confirmation of submission or redirects. It is as if the button is doing nothing. Again, just from the user side.
Caching and optimization are known to cause issues. The documentation recommends excluding pages that include forms from those features. With Cloudflare, it is usually their Rocket Loader feature that causes JavaScript issues, that can prevent the form submission scripts from running.
