This happens for me as well. I'll get the notification like 20, 30, 60 min late. It's random. Sometimes notifications will be instantaneous. Sometimes delayed. I hope it gets fixed. Never had the issue on V5.
Just wanted to echo that I too use pushover to get rich notifications when an event happens. I have Sighthound email the pushover email address the picture and it comes through with a rich notification. Not ideal, but definitely works.
On the iOS app, the clip view order is time descending from present to past. On the Desktop app, the clip view order is time ascending from past to present.
Could you put in a sort order option so that we can sort either way?
