I'm completing a capstone assignment but the page where I should be able to upload my assignment doesn't offer a button to do so. I'va already flagged this three times but unfortunately no response whatsoever. What should I do now?

@Mira G , if you are sure this is a technical issue, then you should report it to the Help Center and find out if they received the flags. 
Try this link:https://learner.coursera.help/hc/en-us/articles/360036160591-Get-Help-with-Coursera

Log in.

Scroll down to where it says “email us here”, here being highlighted in blue. Press that and you should be able to report this.
If this doesn’t work, scroll further down, past the yellow thumbs up signs, will you will see a small rectangular box with a little envelope icon in it that says, “contact us.” Press that box. I hope this helps you.

@Mira G , thank you so much for letting us all know this has been resolved. 😀
