Quick announcement everyone!
We just deployed the option when upgrading your existing page to the new responsive engine to upgrade “as is”. This means everything will be converted into fixed containers and your page will be structured essentially the same as it was before. Based on feedback, this should make converting more complex pages more straight forward. This does mean, however, that your page will not be responsive after the upgrade - you’ll still have to update your page and containers to responsive container layout types based on the responsive behavior desired.
The option to convert your page to the new responsive engine and match responsive behavior does still exist, but will lead to the extra groups required to map the old engine to the new engine.
We hope that this optionality will help you choose the best option for your use case. Look forward to hearing your feedback, thanks all!
