Hi Peter,
We have currently Ambition Pro version 1.0.7. We don’t have automatic update. You have to manually update it. Download ambition pro latest version from your account page and remove old version and install a new version.
If you have not made any code customization in your site then no worry. Your content and settings nothing will be lost while installing fresh download. If there is code customisation in the theme file then we always recommended you to create a child theme so that while updating to new version your customized code will not be lost. So better make a child theme if any changes is required in the theme
Thank you!
