Why wont Galaxy S20 apps run in background properly?

[Android Central Question]

Dear reader,
I have a Galaxy S20+ and I like using apps such as Tile to run in background with battery optimizations off, however, the problem I am having with this is whenever I go to switch from 1 app to another and then return I keep finding all of my connections between my tiles lost as if it was not aloud to connect to my tile devices whilst running in the background.

Yes, my location services are set to always on, permissions are all granted, and Bluetooth is left on.
If anyone has *any* advice as to how to get my Tiles to be able to remain connected to my phone even while my phone is in sleep mode *please* advise me on what I should do. I've been spending hours on this and I want to be able to use my tiles to call my phone again like back with my old phone. Not only my tiles, but also my autosync app and any future apps I want to be running in background.

Thanks,
Dale

You can lock apps to your recent apps list keep them from clearing out ram and refreshing
