The mechanic he is talking about is: If a android or ios player has not enough bread left and tries to launch an attack, he basically has 2 options: Either buy a complete silo refill with gems (this option is also there for windows users), or try to watch a video to receive enough food for 1 attack (not available for windows players, and not available for dungeon missions for anyone). The amount that you get there varies (e.g. if you have 60 bread left and need 100 for an attack, you’ll get the difference 40 bread from the video).
So far the theory. In practice, most often you either get no reward, or 1 gem instead of all the bread, or an error while watching, or no offer at all or… (see bug report topic for full detailed list
So… the issue Dels mentions is that you might see a player with good loot (let’s say 500k) and try to attack, then have to watch a video to gain the food, which may take 1 minute. Then, after the video ends, usually the bread is used instantly to start the raid automatically, with no option to see the base preview again. This means that the player may have got attacked by someone else, meaning the high loot is gone when your attack actually starts and you have no option to say “no, don’t do this”. Also, after 1 minute of video watching, it is hard to actually remember how the base preview layout looked, so you start a raid with thinking “err… what did the base look like?”, in comparison to a regular attack when you see base preview, tap attack and raid starts without interruption…
Thus it would be nice to return to the base preview screen after the video ends, and then have time to look at the base again and decide whether to use the new bread to start this attack or rather search for another enemy.
Currently, there’s a work-around: Try to attack a player that you know is currently online, and then watch the video. After video ends, you’ll see a “this player is online” message as usual and then you have the bread and can choose someone else for your attack. But that feels uncomfortable, not very clean and… you know… not the way you’d want to do it.
