First is the issue of my zap disappearing after I must have posted. That now made me to begin to copy my thoughts first to my clipboard before clicking on post so in case it doesn't show up
Interestingly, my previous zap has disappeared. I am observing though.
I had only migrated to @Zappl yesterday after 
Another thing I notice is the delay.
There seem to a lot of lag time in between writing a zap and having it posted.
For this particular screenshot, it took over 2 minutes before it came back to tell me to repost. How it showed up here on Steemit is a surprise.
Those are the 2 things I have observed so far. I only thought to create some awareness.
However so far, I am enjoying the short approach. I enjoy zappl best from desktop, as that seem to be easier to manage.
What are your own observations so far since using zappl?
