I wanted to add an icon, done, wanted to add a 2nd icon... won't work !
Then I realize that the icon that I'm trying to add is not in the version of Font Awesome available in Dayback, so don't use the current website https://fontawesome.com/cheatsheet as some may not be available !!
Now how do we update the current 4.6 2016 to the current free version 5.6 ? as the file provided and copy into the temp folder are not the same as the one provided with the download from Font Awesome's website
In my case I was trying to add the calendar-check icon


Thanks,
JF
