The issue I am having is that the wysiwyg text controls for the public notes, terms, footer, etc. on any invoice I make have disappeared. They used to be there, but now they are not.
At one point I enabled markdown in settings via Account Management → Overview → Enable PDF Markdown to try it out. I didn’t like the way it formatted a block of fenced text (instead being a block of text with newlines, the text ran into one long single line), so I turned it back off. It feels like disabling the markdown setting didn’t actually un-set the config, because the wysiwyg controls have not returned. Yes, I did click “save”.
The ‘app’ link is for the new web app. The old web app will deprecated in the future but it’s also available as a desktop or mobile app which will remain.
