Unfortunately some 3rd party apps might have compatibility problems during the Beta 😔.
As long as the binary is not certified by Google, Google Pay will not work; however, you can use Samsung Pay application instead.
When it comes to Netflix, it is possible to use it by getting back to the previous version of the system (Android 10) with the use of the Smart Switch app on PC, and then update the Netflix app to the latest version. Next, join Beta Program once more 😉.
If there are issues with other third-party apps, you can let us know about them via the Samsung Members application. There is a chance that our developers will be able to fix the issues quickly .
