Starting to crash

Worked fine for a couple of months. Now it closes when you open it. Not all of the time though, so difficult to tell what might be causing it. Sometimes it closes immediately upon opening, sometimes when you enter a value, it even works sometimes but uses very old currency rates even though I have updated it before. It also claims 'never updated' on the bottom of the page, which it not true. Have removed from phone and re loaded from a fresh download but it makes no difference.

Currency hasn’t been updated since Feb 2018

Been using this for currency conversion whenever I travel only to discover today that the fx rates were incorrect.

All other converters work fine

The Currency Updating Function had stopped working about 5 weeks ago. Bought the Premium Version thinking that’s all that was needed. Even that didn’t work and I had to pay for the new version!! This is FRAUDULENT and must be investigated!!!
