millions of problems with android 9.0

[Android Central Question]

when I saw videos on youtube of android 9.0 I thought it looked absolutely horrible and said I wasn't going to get it. however earlier today I got an update that just said "this update will improve speed and performance" I just thought ok that's fine and downloaded it. little did I know it also installed the pile of **** that is android pie onto my phone, therefore, making it unusable. I can't get anything to work right nor can I find anything and on top of that most of the themes I have paid for don't even work anymore therefore just being a massive waste of money in the long run. I just have questions I hope people can answer.

QUESTION 1
============
Can I downgrade back to 8 without losing everything (factory resetting/reflashing)

(if not then help me with these other questions)

QUESTION 2
============
why does the taskbar at the bottom never go away now? I would like to use all of my screen not 90% of it

QUESTION 3
===========
can I fix the tab menu? I do not want to swipe up. that feels awkward as ****.

QUESTION 4
===========
can i get refunded for my themes?

QUESTION 5
===========
why don't my notifications naturally show up on the lock screen? I would like to be able to read them instantly not have to swipe down to see it

Sorry if I sound a bit mad but I am. I didn't want this update and I didn't want to be tricked into updating to it.

thanks for answering (if you do)

Assuming you're talking about a Samsung...

1. No. Downgrading means you'll lose everything.
2. It's either that or gestures. Settings>Display>Navigation bar>full screen gestures on>gesture hints off
3. Tab menu? Do you mean app drawer?
4. AFAIK no.
5. This was what Google did so Samsung had to follow. Samsung does add an option to go back to the old view. Settings>Lockscreen>Notifications>View Style>Set to detailed or brief.
