As I read in an old forum post from December '17, formerly the custom.css was overwritten by updates like 1.0.2. Now, the update to 1.0.3 deletes the custom.css ... what is not a fix... the result is the same.
So where is it save to I do my css-customizations from now on? May I put my backuped custom.css back into the css-directory and you leave it alone in future updates?
Kind Regards
