A TV build and a phone build of the same app can behave differently.
Ask about compatibility
“Which player and login method are supported on my exact device for Android TV IPTV players?” A TV build and a phone build of the same app can behave differently.
Ask for a repeatable answer
“Can you confirm the current terms and a way to test this case?” Check remote focus, back behaviour and the on-screen keyboard.
Ask what changes
“If I renew or switch devices, what happens to the account, app fee and guide?” Installing an unverified APK or the wrong device edition. Keep the answer with the order record.
What to do next
Open the relevant brand page and check the original supplier information before ordering. For a technical issue, write down the device, player, connection and one reproducible example. For a price question, ask for the full charge in the currency you will pay.
