I published an app on Bubble, but I see many references to Bubble in a “Twitter” meta when looking at the source code. Also, there’s an image link embedded in the source code.
I already cleaned up all the descriptions in the “Settings >> SEO metatags” section, checked in the pages - index, header, footer (which I’m not using), and there’s nothing on the referencing these tags or Twitter. I don’t have any plugins installed in this app as well, aside from the standard API plugin.
