switching off Email notifications doesn't work

I can switch of and submit, but when I reopen the same screen again later it's on again.

Is it just me or a general problem?

Fascinating! I have the exact opposite problem. I cannot enable notifications - I check the checkbox, press submit, and yet the box shows as unchecked when the page reloads.

Still, this thread won't get the required attention. Better would be to log a bug on the bit bucket site.
