I wonder if it is because I don't have lightning on my phone and you were zapping a post from my phone. I mostly use my laptop because I hate typing on my phone, but I occasionally post a picture I took on my phone on Amethyst on my phone so I don't have to transfer it or email it to my laptop. Maybe if you zap that post it fails. That is the only thing I can think of. I normally always have alby and multiple clients open and setup on my laptop.
