Hello, @jayy
Thanks for your patience.
We apologize for the inconvenience you have faced with this plugin and its functionality.
After a careful analysis of our capabilities, we found a way to improve the plugin, as per your request 
Now, you will be able to limit the number of symbols not only for writing the text but for the copy\pasting it in the input.
However, please allow us to mention that this restriction will work only in case, you will choose the “Limit by All” in the plugin element settings:
We always strive to provide the best support and we really try to improve all our products, as it requested 
Please upgrade your plugin to the latest version and give it a try. It will help you to work with an upgraded version of the plugin.
Hope that you will enjoy it.
Best regards,
Zeroqode Support Team
