Hi @Abessolo and welcome to the community.
I have had this experience before and it seems like you will need to update endpoint URL which carries your data.
Taking from this article - Connecting to your data using synchronous exports — KoboToolbox documentation
-
Create another export of the data and make sure the new fields are included in that export - This creates another endpoint URL.
-
Check the endpoint URLs - You should be able to see two URLs now and take a look closely on the versions of these URLs. In my case screenshot below, notice that the first one has all the fields while the second one only has a few fields exported.
Use the URL version that caters for the new fields and you’re good to go. You can just *Update the connecting settings in PowerBi.
Hope this helps.
