Find the seller rather than infer it from the screen
Check the original subscription receipt and account billing record privately. Write down the seller and whether the old product was sports-only or a combined entertainment package. A Fire TV device can be used for different services, so remembering that the programme played on an Amazon device is not enough to choose a transition branch.
For example, a viewer who searches every Amazon account area without retaining the original receipt can mistake a missing app entitlement for a cancelled Prime Video channel. Identify the transaction first, then open the official migration guidance for that seller. Keep the account address private and avoid exposing an order number in a public forum.
Apply only the matching migration branch
HBO Max treats several other old sellers differently: its help routes qualifying direct, Apple, Google, BT/EE and O2 sports-only subscribers to HBO Max with discovery+ credentials. That is a separate instruction from the Prime Video continuation. Do not apply the familiar password instruction to every subscription merely because all formerly used the discovery+ name.
If the original seller is still uncertain, ask billing support to identify it before attempting a replacement order. Keep any continuing subscription visible during that enquiry. A failed sign-in on a new app cannot by itself establish that the old payment route has ended or that another purchase is necessary.
Separate migration status from a playback error
Once the correct route is identified, record whether the current service recognises the subscription and whether a particular programme then plays. Those are different checkpoints. A recognised Prime Video entitlement with a video error should not be described as an ended Amazon Appstore plan, and an ended plan is not simply a television pairing fault.
Give the appropriate support team the original seller, product description, transition question and current message. Keep billing identifiers within its private support channel. This process prevents a device brand from replacing the actual subscription evidence and makes the next step about the correct existing arrangement.
