When trying to download any app from play store: "That item isn't available for purchase in your region" message pops up.
As my country is not on the list when selecting tv region - I've tried selecting "other" option as well as some neighboring countries and some random ones, same result.
Tried making a fresh google account but that did not help.
Can't sideload any apps since for that I would need some file manager app which I can't get from the play store.
Don't know how to fix this issue or how to bypass play store without a third party file manager.
I'm not sure how to resolve this issue with the Play Store, but the Aurora app can let you download Play Store apps without region or compatibility checks. You might try that as a workaround.
