Version 1.6.1 has been uploaded to Apple.

All known network and connection issues have been solved.
Additionally, the search time that is required to detect and connect to a device is significantly reduced.

• myTifi Remote only received the first response that was send by all network devices. If this wasn't from a Samsung device (e.g. Philips TV or media player), it couldn't connect.
  In version 1.6.1 ALL responses from multiple devices are analyzed. Non Samsung devices are ignored.
  To give you the fastest user experience, myTifi Remote connects to the first responding Samsung device.
  In case you have multiple Samsung devices connected to your network, this might not the desired device.
  
  You can click on 'More devices' to see a list of all discovered Samsung devices, and easily select the one that you want to connect to.
   
• When resuming from the background or lock screen, the connection to the TV was often lost.
  This is solved by introducing an auto-reconnect feature, that only takes 0.3 seconds* to reconnect to your TV when resuming.
  
  When you have multiple Samsung devices, the reconnect is done with the last TV that did connect successfully.
   
• Minor corrections are made to the German localization.

It is expected the update becomes available in the next few days.
