We were using custom UI with inbuilt sendPayment intent. Before 17.0 version, the final handle function would call the custom UI configureView method to show final success UI. However, post 17.0 this is not working the final handle function is not invoking configureView of UIExtension. Please suggest if we have any fix for this issue.
Do you get the same results with just the relevant code in a small test project? If so, please include than test project with a bug report to help us better understand what's happening. Once you open the bug report, please post the FB number here for my reference, and we can take a look at the test project to determine if there's an issue with your implementation in the test project, or a bug in the system that requires further investigation.
If you're not familiar with preparing a test project, take a look at Creating a test project.
