Not Liking Snapchat The Last Few Months

Snapchat has deleted an over 100 day streak TWICE now with no timer involved. There wasnt a timer. So explain this. Also Snapchat on the camera screen has been freezing into a black screen with multicolored lines that wouldnt go away and would take me off the app. Snapchat should also make a notification that tells you that you and another snap chatter has a timer.
