We have one Android application that loads a webpage via ChromeCustomTabs. Inside the webpage 2 things happen sequentially.

1. We call script A, that sets some cookies on the mobile browser.
2. We call script B that reads the cookie set by script A.

On some Android devices of users, we are seeing that, either script A is not able to set cookies or script B is not able to retrieve already set cookies.

Are you aware of any tools, scripts or settings (except disabling cookies on mobile browsers, which we have tried already) that may lead to such scenarios?
