The Samsung swipe keyboard method appears to be broken in Knox.
If activate Knox for my work apps, and then try and turn on swipe keyboard entry it fails as it can't download the predictive text library (which makes sense, because Knox/work profile isn't secure if you can download arbitrary files).
Is there any way to pre-load this file or get it added to an os update? It works outside of knox.
I didn't have to do this for previous versions and I don't know where you work but asking a 250k person company to change their settings due to a random change from Samsung doesn't have a great chance of succeeding.
