Rounding in Zoho Invoice for Mobile

Rounding in Zoho Invoice for Mobile

Hi, I'm using the mobile Zoho Invoice app. When I add a new expense (50 euro) with 21% VAT, it is rounded to 60 euro (it should be 60,50). But when I do the same on the desktop version it works correctly.

How can I prevent the app from rounding?

Thank you!
