Howdy,

Thank you for this great module!

Just wanted to let you know that adding the license URL line to tiny_slider.libraries.yml as noted here did in fact make the warning message go away.

Since this fix is working, it would be nice if a new version of the module with this change to tiny_slider.libraries.yml would be released, so that sites can update. ;)

Cheers!
