When i submit my work, i'm left on "please wait" for about a second and then it returns to the "submit exercise" button. I've included a title, sketchfab link in description and sketchfab link in actual place my sketchfab link is supposed to go in the 3rd container. I get 3 green fields so i assume it's all correct and then when i submit it, it just does not work
There is problem with submitting. You need just to click one time and that's all.
Check out submited works, there's a lot of yours :))
pptaszqq is right, and it's definitely a bug that we're working on fixing as soon as possible.
