Level Spring Arm Camera not spawning after upgrading from UE4 4.18.3 to 4.20.2

So I’ve made a spring arm camera in version 4.18.3 of UE4. I ended up placing the camera Blueprint actor to the level. I then upgraded to 4.20.2. Afterwards, I’ve took notice that when I press play in editor, it shows the default “Third Person” camera view and ignores my Spring arm camera viewpoint that I’ve used in version 4.18. How can I fix this?

Is it better to attach a spring arm camera to a character(BP) or to just add the camera to the level? And why? Thanks for your time.
