Hi,
For this query, “But I don’t want to set times can a user take this quiz to 0. I want that each visitor could be able to answer the quiz one time.”
You will have to set the setting ” how many times can a user take this quiz” to 1.
For this query, “Also please suggest me a ways to change the way that this plugin gets Visitors’ IPs to a way that it gets them from ipify.org service not from the server.”
To get ip from ipify.org we need to call ipify API. So we can consider this as feature request and this will take time as we are working on version 7.0.
Hope this resolved your query.
Kind regards,
Kriti
