Yes, I'm writing these comments from mobile version of Ecency web and it's really fast here. The only bug I've noticed when I am writing big comments and type fast sometimes it stuck (I can not press anything and my phone is not responding but after some time it is getting back to normal. I don't know if it is related to SwiftKey keyboard with swipe gestures or maybe it is connected with Preview feature here. Now I'm trying and everything is working fine. Last comment had that bug. Will try to test it out and see if I can reproduce it again.
