I have two devices from which I control my S50, an Android tablet and an Android mobile phone. At various times, these two devices can be connected to either a home LAN or to a mobile hotspot.
I keep encountering a situation where neither of these devices will connect as Master. BOTH are flagged as Guests and so I cannot get access to the unit.
I have gone through many hoops, disconnecting and reconnecting the networks, shutting down and restarting the S50, and nothing works - at least straightforwardly - the S50 will not recognise either the tablet or the phone as its Master controller, and I cannot gain access to it.
So ZWO, what is the recognised procedure to get out of this deadlock ?
