Thank you for your report!
However, this issue is Invalid.

Issues such as these are often due to a temporary service outage, and are handled by the team outside the bug tracker.

Watch Mojang Status for official announcements, or Downdetector for community reported outages.

If there is no general outage, please first try to verify that the problem is not with your local connection or network settings. Afterwards contact Community Support for assistance and refer to this ticket (e.g. "I have reported this issue on Mojira as MCPE-XYZ.").
You might also try to deactivate any VPN in use, and check your firewall settings. If your device supports mobile data, try switching to wifi. If possible, try using a different wifi network.

If you are still unable to access a paid service such as a realm or purchased content, please contact Mojang Support.

What a load of crap.  This has been an issue for me on PS4 for at least three weeks now.  This is not a temporary service outage issue. 

I have been getting the same level of dismissive messaging from every tech support person I've been in contact with from this company.
