Hi @karstjr,
Greetings from the Roku Community!
Please be advised that you can get back in with your subscribed accounts by putting in the credentials that you used from the said channels. It is possible that you have been signed out, but you still have those accounts as long as you sign back in. If, in any case, you forget your credentials, you can reach out to the channel provider's support directly for assistance.
We hope this helps.
Kind regards,
Eunice
