Hi @EugeneSytnyk thanks for using the Braintree SDK for Android. Are you able to reproduce this 100%? Also what version of Android are you using?

Hi @EugeneSytnyk thanks for using the Braintree SDK for Android. Are you able to reproduce this 100%? Also what version of Android are you using?

Yes, this is reproduced 100% of the time. Of course, with StrictMode enabled. I tried Android versions 26, 30, 33. But I’m sure that it can be reproduced on any Android
