What happened to the 'Keep app open' button?

[cyberman3000]

It's totally disappeared!

This function was used to stop the app going to sleep.

Device/ software version: 

Samsung Galaxy A35 / One UI 6.1 / Android v14 

This still exists on my S22+, when I do this:

Multitasking recent apps view> tap app icon> tap 'keep app open'.

Does 'lock this app' mean the same thing?

Is there a need setting somewhere to enable this? Has Samsung removed it from the A series? Did I miss something?

I believe so, in a way. Locking the app means that it cannot be closed from recents.

Looks like keep app open is no longer available as of one ui 6.

Incorrect, this problem predates the One UI 6 update

Newer updates remove this functionality. To do the exact same job, open

DEVICE CARE -> MEMORY -> EXCLUDED APPS.

This does the same function, not letting the selected app go to sleep, keeping it running in the background when the phone optimises automatically.
