Is it possible to share an uploaded qkview with my team mates?

I guess sharing is not possible. Share your credential to team mate.

DO NOT share your credentials with your team mates. You may want to make a "shared account" or there is a new option for "Shared QKviews". There is not much info on how it works (that I can immediately find), but you may be able to share your upload with other members of your company from there.
