I use Netflix, Paramount+ and Prime on my Roku and don’t recall having to log back in.
As far as I know, pay services (like the ones I just mentioned) manage their own account status (log in/out, payments, etc.) Many of them come with certain limitations like a maximum number of devices attached or simultaneous streams.
If you have a large-ish number of devices, you could be knocking some devices off. For example, on one forum, someone was complaining about someone else using his account and having no way to sign off other devices. Someone responded that all he needed to do was log in himself on 3 devices, and that would force all other devices off, since that particular service only allowed 3 devices - the last 3. (Including phones and computers – in fact even being logged in through more than one web browser on the same phone or PC can count as more than one “device” to some streaming services.)
Also, be careful when starting an app to take the right path. Often there is a big highlighted selection with a label like “Get Started!” It seems like the obvious thing to select. But on the same screen there may be a less obvious “Sign in” that you really want if you already have an account.
Banned but back. Because why not?
