Crashing all the time :-(

After last update the app is always crashing when authorizing transaction by fingerprint. I have to launch app for the next transaction again and again. I am running this app on my iPhone 7 Plus powered by iOS 10.3.3. Hope fix will come soon.

Nice job CSOB!

Well done app, much appreciate the comfort. I really hated those SMS keys with passion and thanks to this they are a thing of the past.

Feature request - could the PIN be replaced with a fingerprint scan please for even faster authorizations?

Fix the payment authorization!

The old version was amazing, but this one crashes all the time. The authorizations don't go through. Whenever I want to authorize a payment I need to restart the app to be able to load. I hope that this issue gets fixed. Very annoying...
