My Blackbox Pro app on my ipad has been working well to view streams and recordings from my Zgemma h2s. However I have inadvertently changed the Zgemma IP address and now the Blackbox Pro just freezes with a blank screen. I tried removing and reinstalling but has the same result. Blackbox does not appear in the ipad settings so does anyone know how I can change the settings to get it going again? I'm pretty unfamiliar with ipads - might there be a text setting file I can manually edit?
