Problem with links in labels

I have some links in sub labels in some dashboards, allowing easy access to the web interface for various appliances.

These work fine in v3 but in v4 the dashboards just sit waiting constantly!

Also can’t add a link to a sub-label it wont publish, has anyone else got this working in v4?

I’m unable to replicate this. Which version are you using? Is the link HTTP or HTTPS? Is it on any particular tile?
