I don't know if it's just me and my internet connection. But, I only experience this on sumo. I find I have to hit the fave button multiple times before it will register. And, commenting is the same way. I finally give up on comments because I either don't have to time or just get sick of trying. Sumo seemed much less buggy a few years ago. Now everytime I come here I find something annoying...
I have the same problem with slow commenting! Navigating inside Sumo is almost impossible!!! Many have also saving problems and we really want to have some replies from Sumo!! The users have fled to other drawing programs and it's quite dead here!!! I'm afraid the rest will leave soon if the situation will continue like this!!!
I also have this problem (the comments appear twice) and still no answer to my problem of bug .... and it is true that feels abandoned while we pay for the Pro mode! ! : (
I am frustrated to the max with it! Commenting is so laborious I can't handle it anymore. And I have to upload via my profile picture. To many issues that I think I'm going to step away for a wile. It's taken the fun out of it for me!
