Indeed, I had the same feeling after I posted my first photo through the app. On one hand, it feels annoying, on the other, it actually reminds me of the early days of Reddit, when the service randomly rejected posts for no obvious reason. I doubt that the the problem is really within the app itself, as much as the entire network feels a bit under heavy load to me. No wonder, everyone wants to make money off of crypto these days. I guess, we should be a little more patient with the whole thing and watch grow into a full blown service.
