@anuj9122, sorry that you are still having issues with the plugin. I copied the code above and paste it into the block editor using the shortcode block and it works for me. You can also use the classic editor.
The quick download button does not have a pop-up. It works 2 ways, it can open the link in the same window (current tab) or open in a new tab.
If you don’t want the link to open in a new tab, please change the open_new_window value to “false” like below:
[quick_download_button title=”Download” color_bg=”#ffc107″ open_new_window=”false” wait=3 msg=”Please wait 15 seconds” url_external=”https://google.com”%5D
This will open the link in the same window (current tab). Please let me know if you are still having issues. If possible, send me some screenshots narrating the issue for better understanding.
Thank you for trying the plugin.
