I have trouble hitting back button on ios app, would like bigger button. Something easier to touch.
Agree! (and I’m not even in Beta) Very difficult to tap on the <– in corner of screen. Plenty of room to add a button, esp. on an iPad. 
Indeed, the button’s touch-sensitive hotspot seems to be too small or in the wrong position.
When viewing live or recorded playback in fullscreen, the back button is shown as e.g. " < Wcam1". Normally in iOS (e.g. in the “Mail” app), the botspot covers both the left arrow icon and the label. But in Wyse if I tap the camera name “Wcam1”, it doesn’t go back; instead the top menu row just disappears – very frustrating!
iOS app version 1.1.46.
