Stream+ activation cancellation issue

Stream+ is already showing in my account, and I successfully activated Amazon Prime and Disney+, but I noticed that the home security service is missing or may have been unlinked from my account. When I attempt to re-link the home security, Stream+ returns an error message: 'Sorry, your subscriptions list is not available at this time. Please try again or check back later.' However, Stream+ appears to be fully activated, as far as I can tell. I would appreciate it if this issue could be resolved so that all my services are properly linked and functioning.
