EDIT:

In which case, similar to the banner issue from a previous update, you can get a different launcher (see comments for FLauncher) to avoid it

Is it difficult to install? Like do I need to side load it or can I install it straight from the UI? I am definitely over Google shoving non-stop ads into my paid for experience.
Nope. Just install from the play store.
Is there a way to get it to launch automatically without sideloading anything?
