I tried to click the cursor as you said, and passed the mouse veeeryy slowlyyy through the button a lot of times but it never turned grey to click it, i saw someone click the button very easily in one of the borders of it (in the top left and the buttom right i think) so i tried to hit those parts but it didn't work, maybe is because of my resolution with my pc? because the cursor of that channel was a little bit tinnier than mine.. I think im gonna still be playing version 0.26 but thanks for the information anyways
