@sshropshire - at the moment, this accounts for roughly 10% of our crashes (our crash rate is relatively low, but this is definitely a standout). Is there information you’re looking for specifically in regards to overall impact? We’re nervous about any sort of crash related to 3DS since reproduction of the issues seems to be very dependent on the bank.

I will have our product team member reach out to the support team in the meantime - thank you for the link.

Hi @josephyanks thanks for your patience. Cardinal is aware of the issue and has informed us they are working on a fix. Unfortunately we don’t have a firm estimate on when the fix will be available.

Is there additional information you can provide about the overall impact on your application? If you prefer you can submit this to our support team and hopefully we can use this information to further escalate the issue.
