More times than not the donate button isn't working correctly. Example: Someone ask for troops and it shows 0 of 15. Try and donate to it though and it keeps saying something like "this ally has already received the maximum amount of troops and won't let you donate anything. Another example. Ally asks for troops and it will show like "0 of 3". I don't think that's right. Another thing is I will be putting in my standard single space troop for a donate and as I'm donating the donate button just disappears but then suddenly reappears.
