Traktor DJ iPhone on iOS 12?

So is the consensus that updating with using Traktor DJ iPhone (1.6.5) from iOS 11 to iOS 12 is a death sentence to normal use of this app?
Is there still workability with Traktor DJ for iPhone in iOS 12, but some functionality is lost? If so, what is lost specifically? All controllers, or just some?

Currently, I'm on iOS 11.4.1 on an older iPhone SE.

 

I'd like to know this too. I'm specifically interest in whether the Traktor Audio 2 mark II works with iOS12. Be nice if there was something other than radio silence about his from NI, given the disaster with a much earlier iOS upgrade that saw the TA2 stop working for quite a significant period of time (maybe the time taken from iOS6 to become iOS8 or around then)

 

Works fine here iPad Air 2

 

the current iPad version (1.6.8) in store is younger than the iPhone app (1.6.5) .. 2 different app versions ! .. so please do not compare iPhone with iPad Air2

The big difference; the iPhone version does NOT support the iCloud technology, the meta data exchange was moved from Dropbox to iCloud (because Dropbox support got sunsetted, which resulted in an updated 1.6.8 with cloud). So the iPhone an iPad app does not sync together any longer (check in iOS files app: you will find a Traktor DJ folder in ipad .. but not in iPhone version)

Quite sure there are some minor differences more, but the cloud issue was the biggest change I assume. And each bug fixing (Audiobus, Audio2 from 1.6.6 -> 1.6.7 -> 1.6.8) did not pass to iPhone. Unfortunatly :|

I do not know if the update from iOS 11 to iOS 12 will result in any problems with soundcards or controller .. but maybe other (iPhone!) user can tell ?
