What operating system and browser are you using? If either are not up to date, then you may run into issues. Here is a lesson on What are the browser and computer requirements for Canvas?
In particular, people have been having issues with Safari recently. Internet Explorer is no long supported at all and older versions of Edge may be flaky as well.
People running in private mode in their browser have been experiencing issues in other areas, perhaps related to cookies getting blocked.
Even outside of the private mode, I've had to go through and enable some third party cookies and found that things work better when I disable my ad blocker for Canvas.
I just attempted this with Chrome on Windows and it worked. I then tried it in Firefox in private mode and it worked as well.
You may wish to try it with a different browser or with some of your extensions blocked.
You may also be able to load the browser's developer tools (F12 in Chrome and Firefox) and go to the networking tab. Then try to update your profile and look at the update_profile call at the top. Did it give a 302 status code or is there some error there? Also looking at the console tab when you load a page or try to save can sometimes give information. If you're seeing an error message, it's possible that the request is never being made.
