having an issue with the new Chromebook Pin Unlock ….I have two Chromebooks …I am on the beta channel on one and stable on the other…I set up pin unlock when it was first released on beta …It only required 4 digits…Now…I’m trying to use it on the stable channel Chromebook and it is requiring 6 digits and doesn’t allow me to change it on either Chromebook as it says pin must be 6 digits …And then tells me my old 4 digit PIN doesn’t match … Anyone have any thoughts on this?
