Note: As of the Buzzy v5 app (released late July 2019), editing or authoring a Buzz requires the app to be switched to Classic View. This will have the same interface (adjusted for mobile screens) as the browser version of Buzzy, so the steps listed below will be identical.
You’ll need to be an Owner or Author of a Buzz to edit the Buzz or add content.
To add content to a Buzz, simply click the ‘Add content’ button  (you’ll only see this if you’re an Owner or Author of the Buzz), choose the type of content you want to add and follow any additional instructions.
To edit the content of a Buzz, simply click on the content. The content you are editing will be highlighted with a blue border, and you’ll notice a button at the top right  - this is where you can edit the settings for this piece of content (eg allowing comments, or deleting it).
To move your content around, click and drag it via the ‘drag’ button .
To edit text or a table, click on the text you want to edit and start typing. Formatting options are available when you select text .
