If you have the app on your phone, you can still use it.
If you want to use the new mobile skin instead you will need to either disable the app, or use another browser on your device and navigate to the site. When you are prompted to use the app, close the prompt. One small devices the mobile site should load automatically (if you are not using the app).
If you are using a tablet, it may not automatically load. You may see the regular web view of the site. That's fine but if you WANT the mobile view instead, scroll down to the bottom of the page and select the mobile skin.
Just to be clear - the mobile skin should work for both android and IOS and is NOT the same as the mobile APP (which requires a download). We have 3 viewing options:
1. Regular full web view - most often used by those on PCs or large tablets.
2. The Forum Mobile APP. This requires a download from google play or itunes and is for mobile devices only.
3. The new mobile skin which will work on any device including a PC and doesn't require any download. The new mobile skin is not better or worse than the app - just a little different
