I am implementing amazon pay on android using web URL and facing this issue.
I am using custom chrome tab and after one payment it start showing error "Please enable cookies to continue"
I have tried to resolve this by using
- CookieManager [Usauly for Webview]
- TrustedWebActivity

From the screenshot, it appears that the page is getting opened in a Chrome webview and not the Chrom Custom Tab. AmazonPay for Native Android will not work on Chrome webviews.
Pls check the code once.
