Hi Sean,
This looks like a behavior not handled. I’ll fix this in the next version.
For now can you make the change below in the plugin editor?
1) Go to plugin editor
2) Select File ultimate-floating-widgets-pro/public/js/script.js
3) Add below code at line no. 151
do_auto_close_time($wrap, 'start');
4) Save file.
5) Delete/refresh page cache (ctrl+shift+f5)
6) Popup will now close after x seconds when opened by scroll.
Thanks,
Aakash
