L950XL DS. I enabled and trained the iris scanner for the first time in months, but now it cannot be removed. If I tap the Remove button nothing happens other than breaking iris. It appears that Remove is removing all training data, but doesn't actually turn off the iris scanner. It still turns on and looks for me (but never "sees" me since the training data is gone). Also the "require sign-in" time dropdown doesn't always populate, it shows blank most of the time. This appears to be a GUI issue since it does use my last setting even if it is blank
I have also had a small number of first-open app crashes. What I mean by this is I reboot the phone, then open Mail (which then crashes), but the second attempt to open Mail works fine. Ditto for Edge - The first time I open Edge it is fine but crashes the moment I access favorites. The second time I open Edge it works perfectly fine. There are a couple others I don't remember off hand. Speed is wonderful, best yet. I've not had a battery issue (except for MS Health on the last builds), but this build seems to be even better. This is the first time in months I've felt the RS builds are going forward instead of backwards
