We installed new V2 Elements - found that our production team on Macs either on Chrome or FireFox could not see elements. ON chrome - elements were invisible - on Firefox the page would not fully load. Just spinning element blocks.
Worked fine on PC on both Chrome and FireFox.
All plugins were up to date, Hosted on Pantheon with Cloudflare no minifi. - tried turning of cache - clearing cache - no luck
Had to revert back to previous version so they could work.
