iOS 14.6 update, iPhone 11 swipe up to unlock working but Swipe up to close app or application switcher not working

That's weird.

In such a situation, I'd contact Apple Support directly, using this link:--> Get Support , or make an appointment and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> Apple – Location Selector

After checking it out, they'll give you all the available options.

Did you clean your screen? (using these instructions:--> Cleaning your iPhone - Apple Support)

Did you try to remove your screen protector, if any?

This may have some relevance to your issue. I was having an issue with accidental swipe up closing games I was playing. In avoiding this I was able to set a delay of holding on the screen for a few seconds before swiping in recognizing the gesture for going to home screen or previous apps. Allowing me to hold and drag icons on the game that were placed in the same location as the bar at the bottom of the screen. I don't remember exactly the settings I did for this but accessibility was part of it. Trying to figure it out again currently. However it's something worth looking into in seeing if you have a similar setting that is causing the swipe up not being recognized due to a delay being required prior to the gesture

Is your issue resolved?Im also facing the same issue

My swipe up is not working while closing application however its working in unlocking the phone so what should i do?

This is obviously a software issue. Too many people reporting this. Myself included. APPLE. GET ON THIS.
