Where did you see this? The champion roadmap from September pretty heavily implies that the new support will be from Piltover and Zaun.
If anything, my money is on Silco being the new support.

I found an app on the playstore named Catalyst. Never used it before so yes it is easy to use but not that in-depth. I hope it helps you!
I know this, but in the champion roadmap they said that the support comes a few patches later after the marksman (Zeri)
"As such, we’ll be releasing the ADC early next year and the support a few patches after."
Zeri gets released in the last patch of January (12.2). Every month has 2 patches. A few imo means 3 or more, therefore the support might be released in 12.5 which is the first patch of March
It has to do with the mythic content overhaul and which prestige skins will get new versions (eg the old skin stays exclusive) and which won't.
Riot talked about it here:
https://www.leagueoflegends.com/en-gb/news/dev/the-mythic-content-overhaul/
"BOTH of the champions we planned to release towards the END OF THE YEAR were originally meant to tie into an event"

I mean there's this but as with every preseason overview this is a "yeah we're aware, we're on it, we'll tell you nearer the time". So we know there's a firm road map for new support mythics, and with the tweet we can but hope it brings them back to a stronger position.
OK. That isn't supposed to be like that...
I'm going to have to look at it.
edit: so I signed onto a few other accounts of mine(accounts that hadn't had access to it), and I didn't have any issues. The part that you showed is just for information. http://grabilla.com/0741e-4ccfd3ed-1099-411d-b7d8-6463476605a4.png http://grabilla.com/0741e-2b8344f8-ed64-4f97-b983-fa5fae5dbe31.png Towards the bottom there should be the various tabs(on mobile it is at the top). If they are not there, I honestly do not know what I could do to fix it...
To edit and use, you would have to make a copy, but other than that it should be fine.
Vertical mouse's help for sure, vertical keyboards as well. It increases blood flow to your hands. I read about it here:

I got my fancy vertical stuff from here: https://www.thehumansolution.com/
But there's plenty of inexpensive ones at Amazon that'll do a pretty good job.
Getting into those trigger points help a lot as well. You probably have them up and down your forearms.
