Thanks thats what i thought of late last night after posting. as the site is for my father i was curious if a simple feature was built in. You guys have awesome support !!! I am happy I made the switch to this theme!!!!
I added a class to each button then used the followingmedia query :
@media(min-width:769px){
.wp-block-button.aligncenter.feautrebutleft {
display: none;
}
.wp-block-button.aligncenter.feautrebutright {
display: none;
}
}
