I tried the 6.7 version and I can see that there is a limit in each category.
I watched 10 vids for green packs and didn't give anymore.
But I can farm for replenish condition (blue button), reds and blues.
so uninstall Top Eleven from my mobile, then go the browser >
www.androidapksfree.com > Top Eleven and download the version 6.6
(it's a safe site, I used that some other times)
Then go to downloads of my mobile and install it
So I 'm playing with the previous version now.
Now I can farm some more greens.
When the button gets transparent/grey (no other available vids) I go to training section > Physio Centre > go to replenish condition in one of my players > the free blue button appears but instead of tab it, I go to stock-greens again and now I can see that there is new available video (but only one or few)
I go back to training > Physio center again > replenish condition > instead of the (new) blue button I go for a new free green.
Repeat ...
* maybe you 'll have to wait 3-4 secs for loading the blue Free button
* Sometimes, for an adv I 've seen before, it doesn't add a green but ok, I managed to gather about 25-26
* You do that only in mobile. Tablet still has the older version (6.6) and in browser doesn't need as there is no farming
