Keep App Open only works for 1 app now?

[Kathrin1]

I noticed that the “Keep open” feature now only lets you keep one app open at a time. I could’ve sworn you used to be able to keep up to 3 apps open using this. Is there any way to bring back the ability to keep more apps open (eg. with Good Lock)?

I can have more than 3 apps keep open. The number of app that can be keep opened is depends on your device RAM or the app behavior. Maybe try using RAM plus to increase the RAM size, or optimize your phone to clear RAM. Then try again.

I just optimized my phone (I have 3.2GB of RAM available) and I still can't keep open more than 1 app!!
