I use outlook web app in portrait orientation on my Android phone to check my official emails. When I want to compose an email, I pinch zoom on compose window so that I can see clearly but the moment I start typing, the page goes back to default zoom level (to fit screen width). I have to zoom in again but sometimes cursor gets lost and when I bring cursor to correct position and start typing, the page goes back again to default zoom level to fit screen width. How can make sure that zoom stays where I want until I want to change it again? This problem is not there in Chrome browser.
