Identify the two activities
Write down whether the second device is failing to sign in, failing to register or failing only when another performance is playing. Those are different observations. Marquee’s current device help distinguishes linked devices from concurrent playback and describes a single active playback within its stated device allowance.
For a useful test, stop the first performance through its normal player controls, then try the second device. Keep the account and title details available. If the second device now works, the comparison points toward the concurrent-playback condition rather than proving that the device is unsupported. Do not erase the first installation just to make that pattern temporarily disappear.
Check which subscription route holds the performance
Marquee’s direct service and channels inside Prime Video, Roku or other provider apps are separate routes. Its television help says those provider apps are not connected to the main service. Confirm which route the household purchased before applying a direct-service rule to a third-party account.
Inspect the receipt and the application used on each screen. A direct app on one device and a provider channel on another can create an account-path mismatch as well as a concurrency question. Keep those possibilities separate. Buying a second route may be a deliberate decision, but it should not be the first experiment when the existing account’s conditions are still unknown.
Plan two viewers around the actual rule
If two household members want different performances, compare the account’s current allowance with the intended schedule. They may need to watch at different times or choose an appropriate independently purchased arrangement. Do not equate adding a device with increasing the simultaneous viewing entitlement.
For each performance, confirm the production and language or subtitle options on the actual player. A ballet, opera and concert have different presentation needs even when access works. Retain the biller and current plan terms with the household setup note. This makes future interruptions understandable as a named account condition instead of a vague claim that the second television is unreliable.
If the interruption happens only during overlapping sessions, record that timing explicitly so the next investigation does not begin with an unrelated device reset.
