The documentation you looked into is for the pro version only. Check here for the documentation of the free version: https://www.intechgrity.com/wp-plugins/wp-feedback-survey-manager/
In practice you’ll need to go to the Settings section to create the survey.
And yes, the ads are there to promote the pro version, but it does not block the free version. I haven’t received any complaint for this, since it does not put any ads on your website. It just shows on the admin backend.
And when you talk about badly written documentation, I am sure you didn’t check the “on page” help (on the top right corner of each of the plugin related pages). Please read the doc carefully, I have done my best to explain it as much as possible. Besides that, on the settings page, each item has an associate help button, clicking which you’ll get information about that item.
And thanks for the rating. You should understand that we do not really force people to buy the pro version. The main difference is, the free version allows creating only one form (through the Feedback > Settings page on wp-admin) where as pro version allows to create as many forms as you want. Please do not spread the wrong news. It is a shame that people who actually find this plugin useful, never puts any review, but those, who can not get the working of the plugin, spreads all bad stuff. I hope I have solved your problem, if not, feel free to open a thread on the plugin support.
