Hi David, go to Appearance/Elements and click on the “Home Header”. You can change the button scroll ID and the button text to whatever you like on the 3rd line.
You can see it here
If you click on the first section of the home page, in the settings area you can change the ID, and then just change the button ID to match it.
David, works fine on my iPhone. Not sure why it wouldn’t work on phones, have you tried a different phone browser? Maybe that browser does not support scrolling??
