I can't update any games.

Could you provide some more details? Here are a few ideas on what information you can add:

• Do you see any error messages?
• Since this is the development forums, is it safe to assume you are trying to upload an updated version of one of your apps?
• Have you made sure to update your apps version code before uploading it?
• Updating your app (similar to uploading the initial version) is a multi-step process. At which step are you stuck?
