Hello from sunny Bali

Am just playing around at the moment (don't run before can walk so to speak) I am using the eCommerce template at the moment (because I have a need for a page like that in a new site)

The thing is I got rid of the links at the top of the page re-named the col from nav inserted 3 containers and set flex to row
but it refuses to do that and keeps the containers in a column all the way up. Is this a bug in the theme or am I doing something wrong

Scrap that
saved & restarted the app and back to flexing ok again, must be just some teething problems
