I have an app with an on premises SQL data source. I used to have a schema called 'dbo', the standard, and here everything worked fine. Due to some changes in the database structure I had to change the schema name to 'ops'. I am owner on the database, but now I cannot see any of my forms in edit mode, and I can't submit any forms. That is, I can't write to the tables using the schema 'ops'.
Do any of you know what might be wrong? Is this something general with PowerApps? I have tried, and I can edit the tables directly in Management Studio, but not through the app.
I found the solution: All the new tables did not have any primary keys, and it works now that they have.
