Apex Legends Can't connect an account to Twitch

Hello, so I have this problem where my twitch doesn't show or give me any drops for apex, even though i claimed them i didn't get them, some of them I claimed about 3-4 month ago or even more(problem.png).

it says to me to manage my EA account, but when i go to official (myaccount.ea.com) i can't seem to find any way to connect it to twitch (I may have missed it because i really didn't look into it for a long period of time, but it starts to kind of annoy me to not be able to get a twitch prime skin even though it's claimed). 

And on twitch when I go to all campaigns where usually it possible to connect an account I don't see the Apex Legends icon, so i can't connect it from twitch either.(problem 2.png)

Can you help me?

UPD: Also, i'm not sure if it's important but, i'm using a different amazon prime account, but it worked before (I have the twitch prime mirage skin from ages ago, got it from the same amazon acc.) so i have no clue if it has any impact.
