I suggest that you all revise the iPhone app to allow for the power-up button to be larger. It is a little hard to touch it with it being the smallest button on the app. Why not remove the ‘bell’ or the wave or what have you and replace it with a full sized power up button.
Agree. I requested this months ago. It is especially key due to our often having sweaty fingers while riding!
It’s also in the wrong place. It’s the only button I usually ever push in the app but it’s the only one which is always covered by chat messages!
Agree.
Mobile app is getting long in the tooth.
Zwift, hire me on the side. I’ll update your mobile app 
Don’t worry - you’ll soon be able to more easily use that Featherweight power-up! We’re just waiting on our friends in Cupertino to give us the thumbs up.
Also, would it be feasible to include landscape mode?
