used to be good, now you can't clear the numbers, for e.g., if the number is 4, you press the delete button, it will change to 3.9999, it's either a dumb design or a serious bug

We understand how annoying that must be. The new version (v4.2.0) has fixed this issue. We hope you'll re-consider the rating after trying the new version.

The exchange rate is not accurate and real time.
