Does this new IPad OS 15.6.1 only offer a 6 digit passcode option for everyone?

Does this new IPad OS 15.6.1 only offer a 6 digit passcode option for everyone? I no longer have the option in settings to set a four digit one, my iPad promoted me this morning “you have 59 minutes to change your passcode” with the options “change later” or “change now”… regretfully I selected change now…. And I HAD to make it 6 digits… so I proceeded to finish and then went into setting manually to opt for the 4 digit code to be set again… and now that option is no longer there for me.

I did just recently download and install “ Google Device Policy “ to my iPad to gain access to my work data and emails…could this be the reason I no longer have the 4 digit passcode option any more?
