For a couple months now since youtube updated I am no longer able to switch between my two accounts. I only have the option to choose my main one or delete my alternate one. This is apparently fixed with profile switching but it appears I still do not have the ability to do this. How is this fixed and why were the updates pushed out in this order?

That makes no sense at all... I just tried it on mine and it works fine. Let's step back a moment. When you added the second account, did you follow these instructions exactly (including signing into the account?) Try this :
First, remove the other accounts (I did this from Settings > Accounts)
After removing them, restart the device (Settings > System > Restart)
Wait for it to boot up completely
Chromecast prompts you with a new feature: Profile TVs and asks if I want to add a new account
Follow the instructions (put email, password, two factor authentication)
I factory reset so yes both account were removed. I signed into my main account, updated the apps from play store then added second account. Yes I am signing in correctly to both, I know how to do that that.
EDIT: After pulling the power and starting up again I now have the ability. I don't know what that was so difficulty. Thanks fo ryou help though.
