Smart Cover issue on iPad running iOS 12.

Actually, this option wasn’t there in iOS 11.3 (with which it came preinstalled) and 11.4 as well, but the cover worked fine. It isn’t working with iOS 12 anymore.

You can see the image I have attached in above answer on this page. The option does appear on searching in settings but it isn’t there under ‘Display and Brightness‘.

I contacted them. The first person I talked to advised me to do a restore from factory settings with iTunes on PC, which I did, but it still didn’t resolve the issue. Then I talked to a second person but due to some issues, I had to suspend the chat. The third person couldn’t figure out the issue, and said that the rsetore should have fixed that issue. She ran a dia test on my iPad, and said that everything appeared to be ok. She told that it might be possible that my 3rd party cover might not be compatible with iOS 12 anymore, and asked me to visit a service centre, as she couldn’t figure out the exact reason for the issue. Then my Apple Support app on my iPad stop responding and the chat ended.

Even the tech support executives aren’t sure about this issue.

Update:

I tried restoring the iPad to its factory settings with help of iTunes on PC, and even that didn’t resolve the issue. It is definitely a software problem.

Are you using official iPad cover by Apple or a third party cover?

I powered off the iPad and then turned it on, but nothing happened. Then I tried your method of force restart by pressing the power button and home button simultaneously. I didn’t see the Apple logo and the device turned off. I waited for a few seconds to let it turn on but it didn’t. Then I started it by pressing and holding the power button and it powered on. But still the issue persists.

Thanks for helping out, but the problem is that this option isn’t available on my iPad, I have attached a screenshot of the same on Page 1 of the discussion. And it didn’t have this option in iOS 11.3 (with which it came out of the box), and iOS 11.4. But the cover worked perfectly fine on both of the above mentioned versions.

One more thing I forgot to mention about that I recently had a talk with an Apple Support Executive, and even he advised me to do a restore with the help of iTunes, and said that if the issue isn’t resolved, then it maybe possible that the iPad no longer supports Auto wake/sleep function in iOS 12. So does that mean that iOS 12 doesn’t support it anymore?

One thing I forgot to mention about the cover.

In the preinstalled iOS 11.3 and 11.4 on my iPad, the cover did wake the screen up when the cover was lifted up, but the iPad didn’t go to sleep when the cover was closed, even on the above two mentioned versions. Now it doesn’t even turn the screen on when the cover is lifted up. The lock/unlock toggle didn’t appear in the Display and Brightness section, neither in iOS 11.3,11.4 or 12. But the magnets of the cover are working, and are able to activate the screen again if closed and lifted again, when the screen is about to turn off.

Actually, finding Apple Support in India seems quite difficult to me. I visited Apple India website, then from there visited the Support section, and started a chat. The executive though didn’t seem Indian, and appeared like he/she is from US or any other foreign country, so it’s a tad difficult.

That’s understandable, but what if the talks finally conclude to setting an appointment with an Apple Service Centre, and then he finds out that I am from India? That’s the main issue, otherwise I have absolutely no problem.

There are a lot of Apple authorised service centres in India, no issue about that. The thing is the coordination between Apple Customer Service in USA and India, which isn’t going to be that easy, as per my opinion.
