question about commonapp essay updating/changing

<p>Hello,</p>

<p>I have submitted three different versions of the commonapp essay to several different schools. However, my commonapp does not prevent me from updating it a fourth time. I was under the impression that it would only be possible to change it 3 times. Is this a glitch in the system or does anyone know what is going on?</p>

<p>I don’t believe there is a limit on changing it</p>
