I assume you remembered to publish your app 🙂
Try in an Incognito browser window, Microsoft is very aggressive with caching, and I have seen cases where only some users doesn’t see new fields.
Or try to clear page personalization for that page. They can also sometimes prevent new fields from being displayed.
Thanks for the response. Unfortunately, none of this helped. Could it have to to with the specific page, posted services invoices?
Please try to send your .app file to support@hougaard.com – (rename to .txt to get through) Then we’ll take a look at it.
