I have a PowerApp connected to CDS and it was all working perfectly. Someone asked for an additional field on a table so I added the field and refreshed the data entry form so the new field was shown. No other changes made including changes to galleries that display the data. It all worked fine in Edit and Play mode. When published, the data entry form worked but the gallery no longer displayed data.
I've tested some scenarios and have ascertained the following
Please help ... I'm going out of my mind as I can't find any logical reason why this wouldn't work.
I've done some more research ...
I've rolled back to the last working version which was bound to the old entity structure ... that worked.
If I refresh the data source but make no other changes to forms or galleries ... it breaks and the gallery doesn't display.
I seem to have a similar problem. In edit mode my gallery is working and displaying a filtered list of Azure Sql Server records. In Published/Play mode the gallery on my app is displaying the correct number of records but the label fields are not being filled - but the checkboxes associated with the data are being filled in. The pictures below I think summarize the situation.
Edit Mode and then Published Play mode
Have refreshed data connections but this has had no effect. The data seems to be retrieved ok but the label controls are not displaying correctly.
Looking at the history of similar issues it seems often related to a Powerapps release. Mine is 3.18124.26.
Do you think this is a similar problem? Maybe you could try displaying a checkbox on your screen of the data. Maybe the powerapps team will have a look soon.
In the ticket you'll be asked for a Session Id, you can find the instructions on how to get it from here: https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/get-sessionid
I created a task as per below link but everything has gone quiet. I was able to work around my problem by setting an advanced option but it points to the advanced setting not working correctly.
