As others have said, I too appreciate the honesty expressed in this post and, without reading every post in every thread, I can’t say what has implemented since your post.
What I can say is I have only today become a Blink customer, buying a three camera system and I’m as disappointed as I am delighted.
I read a series of posts about being able to save or share individual photos, something you 100% agreed with (as many, many others do) back in May 2018, yet still this hasn’t been implemented.
Far be it for me to question the development process of a tech company but I simply do not understand why it hasn’t been implemented.
Not having this feature is frustrating enough (it never even occurred to me that I wouldn’t be able to do this) but it makes me regret even buying the system.
