Hello @prajesh,
First of all thank you very much for using the pro version of the theme.
Now to manage the issue in the mobile and the i-pad screen, please add below given CSSS by going to Admin Panel > Appearance > Customize > Additional CSS.
@media screen and (max-width: 1023px) {
.global-layout-three-columns .site-content .row {
display: flex;
flex-wrap: wrap;
}
.global-layout-three-columns #sidebar-secondary,
.global-layout-three-columns #sidebar-primary {
width: 100%;
}
}
Hope this helps.
Regards!!
