Yes, same bug here iPhone 6 8.3 You can just swipe up instead of pressing done to bypass the crash.

try his beta repo. i have it installed on my 6+ and it works great!

only issue ive had is when i remove widgets or whatever from the NC and press done, it crashes me into safe mode. otherwise, it works great!

Is there a way to merge the Today's tab (with the date) and the Notification's tab?

I found that LockInfo8 can do this, but it boots me into safe mode.
NCAllOnly only removes the Today's tab. If there's no other solution, maybe just the date in the Notification's tab.
