Trouble with boost button ( android)

[summersalt]

My 2x food boost button will not work. No matter how many times I restart game. Since the new version came out it hasn't worked. I have 6 of 8 boosts available. When I push it it will take me to something else such as a habitat. It's not my phone. All other boosts work fine. Is there a limit to using this Boost? I.e. the timing of the food in the farms? Any one else have an issue? Really wanted to boost the food for the extra sweethearts but have not.been able to. So close to earning the dragon and community prizes :/

Yes it's a known bug...

There are 2 ways to get that 2x boost to activate...
1. If you have a farm that you haven't planted, the boost will activate here so you can boost first, plant after.

2. If all farms are working on crops, the boost can be activated by tapping a little outside the plant symbol. I think I was able to tap just below and maybe to left of the picture.

The problem is that the picture doesn't line up exactly with the button hidden under it for the boost. Why they haven't fixed it is yet another puzzle.
