I have a share point list that had 10 fields and in my app a form that shows the fields, and if you update the form and submit it, everything updates as expected. in the source data.
I added a new text column to the Sharepoint list, and added some data to it.
I refreshed my connection to the data source in Powerapps as normal.
I added the new field to the form as it was now in the available fields list as normal.
No data shows in the new field?
strangely, If I type some data in the new field and submit the form, it updates the source data, but will still not show any text in the field.
I have developed 100's of forms in the past and never seen this, and cannot resolve it.
