I have a question concerning the blue un-shaded arrow in Snapchat because I believe there is a misunderstanding or maybe I just dont know how it works. The problem is the following:
About a year ago I had exchanged snaps and chatted with a friend of mine. For the past 7-9 months he had been sending snaps but I had not opened them (therefore there was a shaded red square with the date he had send them). I never opened those snaps (photos) and now out of nowhere the symbol next to his name changed from the shaded red square to a non-shaded blue arrow. How did this happen if I had not chatted with him since 2015??!!
