Yeah,
I restarted several times. Once after updating the extra module URL. Then a complete “reboot system”
Then again after adding that button you shared.
Then again after reloading the other HACS repositories.
(Restarting is my go-to solution for problems… LoL)
Thanks again. Yeah, glad its working again.
Hope the next update is less annoying. (But I will search back to this page to see previous answers. 
)
