Resume position can be stored locally by the app rather than in the streaming account. A second device may therefore start at the beginning even with the same login. Cross-device progress requires a documented synchronisation feature, not merely shared credentials.
Check what the player promises
Some applications synchronise progress through their own user account; others retain it only on the device. The service account and the player’s cloud account can be separate. Do not create a new account with an unfamiliar site merely to obtain a feature you have not verified.
Record a simple fallback
Before moving devices, note the approximate playback time and the title’s edition. Different cuts, intros or episode files can have different timelines, so a time position from one version may not land on the same scene in another.
Respect the active-session limit
Stop playback on the first device before starting the second when testing a single permitted connection. A resumed source request may count as another stream even if the first television appears paused. Use the player’s stop control rather than leaving an old session running in the background.
