Hello. This is related to a question that apparently wasn't answered. I'm having the same problem. When adding alternate layouts to what will be a responsive site, all of the timings that were built in my Mobile (primary) layout are being lost. It looks like I have to rebuild all the timings in each alternate layout. But I'm hoping I'm missing something because that would be an unexpected setback in this process. Was this question ever resolved, and is there a way to preserve the timings that were all set up in the original development layout? Thanks.
