If you are on a browser page in the top right corner you should see your picture. Click on it and in the drop down menu it should say,"edit profile." I haven't tried the app yet, but you can try to open up a webpage on a mobile device (phone/tablet) and go to the site that way too! Not sure if it'll let you access the desktop version though. I know that if you are using a Chrome browser on a phone (for example) that you can click "request desktop site." Hope this helps!
