I am using Lumia 720 with 8.1 Developers preview and Nokia black firmware. The font size on wide tile of WP Central app is too small. It is very difficult to read. Is there a workaround to solve this issue or an app update is required?
Please remember that the Windows Phone 8.1 developer preview is for developers to see what works and what doesn't, including what needs updating. We will be updating the app to fully support Windows Phone 8.1 before general consumer release but in the meantime you cannot expect third party apps to support a preview version of the operating system fully.
