Works seamlessly except the currency converter

Hi, its a great app to replace my calculator with lot many extra features but pls work on the currency converter which will make it a worthy download.

Dear user, the issue of currency converter has been fixed, please check [Settings] - [FP Calculator] - [Wireless Data] first and make sure you have WLAN and Cellular Data enabled. Also you can upgrade to the latest version V1.5.0 to fix this issue.
