New String interpolation function

[londontoholland]

I've tried using the new String interpolation function from this blog post.

It works fine until I save, close and reopen the app and then it seems to revert it back to the old concatenate function

This is before I save and close

And this is the same label control after I re-open the app

Any suggestions?

I suggest you restart the formula again but this time before you close the App, save and Publish.

Hi @londontoholland ,

According to the blog, there is a known issue with this feature when used in some apps that also use service functions through a connector.  On save of the app, $” will be replaced with Concatenate.  The problem has been fixed in 3.22051 which will begin deployment shortly.

In addition, maybe you could try to change your authoring version manually. It works on my side.
