Maybe I'm better off sticking with Airtable

I hope this doesn't sound like a rant, because I really want to like Notion. However, I just can't seem to wrap my head around the UI. I'm sitting here having to manually copy/paste this table of times line by line, cell by friggin' cell from a Google sheet I had to create specifically for this purpose.

No drag fill? Ok, whatever.
No copy/paste the table into the Notion table?! WTF.
Hitting <return> not only enters the cell I want to edit, but conveniently pops up "Accounts & Workspaces" and never closes it?!??!

Am I required to mouse around and click to use this app?

Ok, so aside from me pulling my hair out and wanting to smack a dev, there has to be a logical explanation. There must be a key understanding I'm missing that is the lynchpin to it clicking with me, and then everything will fall under my hands as the intuitive interface I know it (probably) is. Much like going from excel to relational databases for me - it was hard to get it, but now I don't know how I was so daft for so long.

So what is it that I'm missing here?
