I don't know much about PeakD as mostly I am using @ecency. But if any of my scheduled posts didn't go through which rarely happens, I can move them into draft again and then publish them without the need for any changes. But missing the scheduled post can be a little bit annoying since it can affect the posting streak that we want to reach.
!PIZZA !PIMP
Ya I need to figure out if I can get my post back lol. I use Ecency for comments and PeakD for writing and wallet stuff.
