I created a Magento Child Theme under 2.3.0 based on Luma.
I tested in Developer and Default Magento Mode. I expect the custom _theme.less file to be generated on the fly.
But this does not work. I have to run "php bin/magento setup:upgrade
" after every single css line change to take the changes affected in front-end.
Also there is a Child Theme based Folder in pub/static folder. Why is this created? Im running default/developer
mode so i don't expect the system to create any /pub/static/
files?
I already tried cache:flush and cache:clean.
It workes too when i change modes in magento from dev to production and visaversa.
New Info: I added a new .css File to the Theme and it works like expected. So i think the problem with the _theme.less is about the .less compiling is not working on the fly?
