Have three people in the office.  My company file that allows logoff is on my computer but not on the other computers in the office.  Gear button doesn't allow for a logoff/sign-off on anyone's computer.  Cleared one of their Intuit cookies - no change.  Migrating to QB Online was the worst decision I've made in recent memory. Used desktop for 15 years with no issues whatsoever. Why would the online version show a symbol that allows logging off be there one day and gone the next?  A mystery that continues to be permanently unanswered as QB can't update its online program to be friendly to the USER.  Chrome, Firefox, etc.  They have all been around for awhile.  People using these programs is not a surprise.  QB should work consistently on all of them.  I don't think that's too much to ask.  It's really just a matter of QB caring enough to fix the problem - clearly, as of right now, they just don't.  Frankly, I don't expect an answer to my frustration and don't want to spend the time to do the programmers' jobs.  I have my own job.
