Yes, happened to me. not even the length, i think, since i tried both long and short comments, and it didn't take. probably just a glitch, hope it's fixed soon

Same here! I've had this pop up for me as well! I wonder what's going on...

I did recently, I understand that my comment was a little on the long side but even after cutting it down and getting rid of a few repeated words it didn't go through :(
