Sorry to necropost, but the swatches palette really needs dumbing down. I read the mammoth post above and I still didn't have a clue how to add the currently picked colour as a swatch. This is such a basic thing it should be self-evident. I tried dragging, I tried "Add Global color" from the dropdown menu, which opens another window with an identical color selector and whatever I did, I got a black swatch. 
That is, until I saw this icon with the 2px "+" in its lower corner. That's just insane, you're trying to represent the whole swatches palette in one 10x10px icon with all the relevant information in a quarter of its size! Just replace this icon with a full-size "+" and people with normal eyesight will immediately know what it does. You don't need to draw the swatches palette when you're IN the swatches palette. People already know. They're just looking for the plus button.
 

That did it!! Thank you so much!! I must've hit that keystroke combo on accident. Thanks again for the help, I appreciate it!

In View menu, select Show Toolbar or type ⌘⌥T

Hi!
I'm not sure at the moment, but try TAB.

Well I tried checking my history but can't seem to find the pages where I saw that if you had the previous version, you can upgrade for free, and just need to enter in your license.
It's not a big deal at all of course because this amazing app is well worth the price, I just thought why should I buy it if I can upgrade for free? (haha) And yes Psenda, it's possible I saw "update" and took that as an upgrade to V2? 
What happened was, I formatted my computer for various reasons and my husband downloaded Affinity pub for me so when I went in and my license didn't work, I realized after checking my account etc. that I had downloaded V2. Cue my confusion. Anyway, thank you so much for the replies!

Welcome to the forums @Beautiful-Cranberry
You can resize multiple layers at the same time by using Transform Objects Separately (on the Context Toolbar of the Move Tool) but that transformation is relative to the size of the selected layer.
For example, with two rectangles, one of width 100 and another of width 50, if you try and resize the width of the first one to 50 the width of the second one will become 25 (100/2 = 50, 50/2 = 25).
There have been various people asking about absolute resizing of multiple layers but I don’t know if there has been an actual request for this. You could try searching the forums and ‘add your voice’ to one of those if you want to (if you can find one).

It sounds this button is pressed unintentionally:
