Zach is telling you lies.  The company continues to experience these problems, but its CS script tells them to not acknowledge its issues.  I just got off the phone today with a QBO Expert regarding the same issue - specifically in the Settings>Account and Settings>Advanced area.  All the same advice, different computers, different browsers, maybe it's your internet... I tried it all.  Please wait 24 hours.  That's what I'm doing now.  Our team has experienced the same issues for a couple of weeks on one of our files (we have four).  And, who would have guessed, my QBO Expert did some searching and they haven't been experiencing any of these issues.  Looks like you have - and others - as documented here.  But let's lie to our customers, the people who pay our bills.  

Dear Intuit, your users are smart.  Stop lying to them.  And get to work acknowledging your issues and fixing the bugs.
