I cannot access my onscreen keyboard's clipboard when I'm in Zoho's Notebook app but can access it in all my other apps except my Opera mobile browser. "Text copy" is enabled within the Notebook app's privacy and security settings so that can't be the reason. Is this a bug or a security feature?

My Opera mobile browser also does the same thing in not allowing users to access the clipboard within the browser, but that is to prevent websites accessing sensitive info that might be in the clipboard such as copied passwords. However, I don't get why Zoho would implement such a security feature without the option to turn it off, as the Notebook app isn't a browser. Not being able to access the clipboard is a dealbreaker for me in a notes app.
