At the moment to find the link to the talk page I have to scroll to the bottom of the page, which is painful. I like both variants A and B, and both could be supplied at the same time! Variant C copies the Desktop model. It is very uncommon to have multiple tabs this way in an app. Final thought: apps are for people not able to navigate in a browser, and IMHO (nearly) all app functionality can be supplied with a (mobile) webpage. The reason that I don't use the app is that it doesn't offer all the functionality of the Desktop version (and it is painful to scroll down to a webpage to switch to Desktop version).

Hi @Ad Huikeshoven! Thanks for this very helpful feedback its much appreciated. We are awaiting approval from the legal department to launch an in-app form that will hopefully make responding less painful. Once we have the go ahead, we will launch the mobile friendly survey form. In the interim, we have created a button that auto creates a new section where you can respond to the questions if you have an interest in providing feedback to some of the other questions there.
Equally thanks for your feedback of why you don't use the apps currently. Our goal is to be mobile first and not necessarily replicate everything in Desktop but still allow mobile only and mobile first users to fully participate in our projects, in ways that make sense for mobile users. Eventually there may be functionality completely unique to the apps, but we always prioritize not disrupting the workflows of contributors on other platforms. We don't see the apps as a "replacement", rather a supplement. I encourage you to check out the app strategy over on the design style guide.
Thank you again for providing your feedback, it isn't taken lightly and is always appreciated.
