Hi,
I mentioned this about ‘content style 1’ but I am also having the problem in ‘Feature Intro 1.2’.
When I paste text into the block it shows fine in the edit area but when I publish the page, the text where I have used copy and paste does not show and when I re-edit the page the text is not present either showing it is removed by your software, perhaps the parser needs a tweak to allow copy and Paste.
I used text from notepad
my setup:
Joomla 3.6.5 JA Builder 1.0.0 Beta Windows 10 64-bit used both FF51 and latest chrome
Update
if after I pasted the text in i type a couple of letters the text stays. This must be related to some javascript trigger. I have not done anymore tests and have not done exhaustive tests on this.
