The latest updates to the Periscope app are controversial. The fast forward option is brilliant in replays (scrubbing) as it allows you to skip to any place in the replay – for example skipping any long introductions at the beginning, or rewinding if you missed something.
The replays on the map are great for viewers, as they now give you access to far more content on Periscope, but there are privacy concerns for broadcasters as it would allow potential stalkers to find the precise broadcasting location of any user.
Please see my other blog post about how you can change your location if you are broadcasting on Periscope from an Android mobile device. Unfortanately, this is not possible on iPhones.
