Here will be the advice from my coder for you:
- Updating theme (update the theme to the new version) means that we will update whole files and folders, not update each individual file. The things in changlog.txt are just the big changes, need to pay attention, and it does not the whole change of new version. You should not custom deeply in Main theme. It will be changed in the next update versions by that customization.
For example, you should not copy then redo whole file: css": css / woocommerce.css & css / woocommerce.min.css.
If you still want to edit any css codes, you can copy and edit again that CSS LINE only. You can copy and edit any css editors except Main theme:
+ Theme Options / General / Custom CSS/JS / Custom CSS
+ Cusstomize / Additional CSS
+ Child-theme / style.css
=> So, the solution for you is: You should backup again your site (your customization if you also did it in Main theme) and update the new version of theme normally. Then, you can check again the customization you did before and re-custom if you see it is changed with Main theme.
Hope that it will be useful for you
