Your device probably is a low memory device.
No judgement there, low memory devices are all that I have, lol.

But yes, this can cause some compatibility issues with certain apps.

On this device that I am using, I cannot allow other apps to have notification access.
This makes it impossible for me to fully integrate Greenify, which I have done on all of my other devices.

Such is life.

It sucks sometimes, but you either get used to it or else buy devices that are compatible with the apps you desire to use.
