Can't connect to Google Drive – KyBook - EPub,FB2,PDF,DjVu Reader Review

The app gives the option to connect to Google Drive, but always gives an error instead of letting me sign in. It says "Error: disallowed_useragent This user-agent is not permitted to make an OAuth authorization request to Google as it is classified as an embedded user-agent (also known as a web-view). Per our policy, only browsers are permitted to make authorization requests to Google. We offer several libraries and samples for native apps to perform authorization requests in the browser."
