What to do if Netflix does not update after changing Netflix country on Fire TV

On some devices, the Netflix app's home page does not update correctly after switching Netflix countries. This is caused by Netflix caching thumbnails and other data directly to your device.

One solution, would be to simply switch between profiles within the Netflix app itself for it to refresh.

In the Netflix app, select More or Profiles (depending on device) and switch to a different profile.
Now switch back to your preferred profile and the images and visible content should also update to reflect the selected Netflix country.

If the above did not work, you can easily clear this cached data manually by following these quick steps:

From the Home screen, select Settings at the top
Select Applications
Select Manage Installed Applications
Scroll down and select Netflix
Select Force Stop and Clear Cache, exit the settings and relaunch the Netflix app

Alternatively you can also power cycle your device to clear its cache like so:

Turn off your Fire TV device
Unplug it from wall power
Wait the full 30 seconds then power it back on

In most cases, this should clear most local app cached files and achieve the same results
