Hello @cmsaatva
Does the issue persists with all types of code. Try to save some analytics code like Google analytics, to check it it's being saved. Also, if possible, do share the code you are trying to save so I could dig if there is any bug. Code sanitization might be the culprit.
Sorry for the late reply. I have been busy since couple of days.
PS: You may DM the code via chat or just email me at anandkumar@protonmail.com
