Autolock

OK, I stumbled on the solution. For some reason the iPad was in Low Power Mode (even though it was 43% charged, and much higher when I first noticed the problem.) Turning off Low Power Mode under the Battery tab in Setting solved the problem.

Sorry about wasting your time.

I do not have a work account on this device. I used to but since they instituted two-factor ID a few months ago I could not get it to work and took that account off. All I have is personal email and an iCloud account.

There is no "Profiles and Device Management" entry under General. There is "VPN & Device Management". When I open that it shows me "VPN Not Connected" and the next line is blue and says

"Sign in to Work or School Account"

When I touch that, it shows me a form that says "Sign In to Your Work or School Account"

When I enter my address on the account I used to be able to access on this device I get "Sign in Failed / Your Apple ID does not support the expected services on this device. Contact your administrator to sign in."

By the way, I get the same result when I try to sign in to that account from my iPHONE, even though the email account still works for me on the phone.

So I tried again to install the work account on the iPad, and this time it worked, without the two-factor feature. Apparently the company reverted to the old signon procedure.

Then I rebooted, but the autolock is still stuck at 2 minutes. This make it really annoying to use the device for a reader, or even to interact with a complicated web page (like ordering from, say, Amazon), because I have to keep unlocking it.

Correction: Screen time was turned on although I do not remember doing so. I just turned it off, and still cannot change Autolock. Will reboot to see if that helps.

No. Under Settings; General; Mail I see only iCloud and Mailfence (which is my personal email).

My office IT is useless. I reset the iPad and the setting stayed stuck at 2 minutes, even before restoring everything from backup. Next stop, Apple support.
