Hi @mrdfrost,
Thanks for reaching out.
The issue is you’re adding IDs multiple times (one for desktop and one for mobile). IDs are unique should only exist once and that’s part of standard. Instead of hiding your sections from devices, hide its row so you only need one ID for that section.
Example,
[section id="david'] [row 1 (hidden from mobile)] [row 2 (hidden from desktop)] [/section]
This is just a pseudo-explanation, but the concept is the same. Use your section to wrap the entire content regardless of device, then use row to display content specific to devices.
Thanks!
