From Sharetribe Flex environments workflow documentation:
no-code changes are made in Test, and get pushed from Test to Live
My question is: how do I actually push these changes?
For example: lets say, I've modified landing page (in TEST environment), does "push" mean that I have to manually replicate changes I've made in LIVE environment, or there is some way for me to transfer no-code changes from TEST to LIVE (using Flex console or cli)?
The Console has a "Copy changes to..." button in your test environment in the Content tab. Clicking that button will allow you to select the environment where you want to copy your changes (live or dev) and determine which changes to copy over.
