GOS is killing apps when I switch away from them, making multitasking impossible. Some apps, like obsidianMD do this more than others. There's a lot of settings to check:

1) app permissions > background
2) settings > battery > battery saver
3) dev, apps, don't keep activities
4) dev, apps, background process limit
5) dev apps, suspend execution for cached apps
6) dev, apps, standby apps

What should I set all these settings to for testing?

    spamrisku2jqqrfh have you tried toggling on the Exploit protection compatibility mode in the system settings for said app and rebooting the device. Additionally, suggest reverting all the listed changes you mentioned back to default first.
