Nabu Casa - need to re-login when HA restarts

I am on HA 2021.1.5 on a debian supervised installation. However it happened on earlier versions, as long as I have been nabu casa I think.

I have a nabu casa account.

Whenever I restart HA the nabu casa url (https://longestring.ui.nabu.casa) becomes unavailable until I go to remote.nabucasa.com and log in again.

Is this the way it is supposed to work? I see from the nabu casa docs that I could set an automation to run the cloud/remote_connect service on startup of HA, but should I have to?

I had this problem sometime last year and sent a support request to Nabu Casa. (There is a support link on the web site.) They advised that it should automatically reconnect and did give me something to try, but I do not remember what it was. By that time I had an automation set up to reconnect on start up and haven’t re-tested without it.
