Moving from one software platform to another can change the player purchase without changing the viewing-service identity. Before buying new software, make a small inventory of the old product, the new platform and the access arrangement you want to retain. The point is to establish what travels and what needs a separate decision.
A familiar icon across two stores does not by itself establish a shared licence.

Separate the three identities
List the device platform, the player edition and the service account as different items. An app purchased in one store is not the same thing as credentials issued by a service seller. This distinction lets you ask a developer about software portability without asking the service administrator to interpret a store receipt.
For a hypothetical move from a phone to a television platform, the desired task may be identical while the available player edition differs. Write down both edition names and developers. Do not describe the change only as moving my IPTV, which leaves the receiving support team guessing about the actual products.
Read the actual purchase boundaries
Check the original receipt and licence description for platform and account scope. Google Play describes use of purchased apps on compatible Android devices under the purchasing Google Account. That statement does not establish an entitlement in a different store or prove that every television device is compatible.
For another platform, use that platform’s genuine rules and the developer’s specific product explanation. Avoid extrapolating a same-account reinstall policy into cross-platform portability. If the developer offers a transfer or shared entitlement, retain its actual conditions rather than assuming the offer covers every edition.
Confirm service fit before replacing the setup
Establish whether the genuine new player supports the service’s actual account method. A software licence may be valid while the desired input method is unsupported, or the reverse. Keep those questions separate so a purchase decision does not rest on a successful download alone.
Preserve useful non-sensitive setup notes before removing the old app. Keep secrets private and avoid circulating screenshots with full source addresses. A reversible transition plan is helpful because it lets you understand the new arrangement before losing the reference that explains the old one.
Price the transition accurately
If new software is required, record its complete cost separately from any service renewal. Do not count the old purchase as a refund or credit unless an actual arrangement says so. A past payment is part of the history, not an automatic discount on another platform.
After the move, save the new receipt and a short note about what was retained, replaced or left unresolved. This turns the transition into a readable record. The next time a feature is missing, you can identify whether it belongs to the old edition, the new software entitlement or the service arrangement.
Useful answers
Does an Android app purchase automatically cover an Apple edition?
Do not infer cross-platform entitlement. Read the developer and relevant store conditions for the actual products.
Can a service account and player licence have different portability rules?
Yes. They concern different products and responsible parties, so establish each arrangement separately.
