We have several Production Apps (SQL as DataSource) that have not been edited in weeks, that suddenly do not allow Patching a Collection. They give error: Invalid Argument type (Table) Expecting a Record. In my experience this would indicate that the Collection doesn't exactly match the fields of the Table it is attempting to write to; however we haven't edited the SQL server tables/settings or the PowerApp in weeks.
On some apps, we were able to get back up by removing the Data Source and re-adding it; however, this only works from within the Dev Studio. As soon as you save/close/re-open the PowerApp, the Error returns.
