If my plugin is expired, will all its features stop working suddenly?

No. However, you won’t be able to update the plugin when new versions arrive. It is not healthy for your website or shop, because using old versions of the plugin may expose it to security threats. So, we suggest you use the most updated version of our plugins always. And when the update we have released is a security update, make sure to take action on it immediately so that your website remains secure.
