Open datapages directly into Grid Edit mode
Datapages cannot currently be opened directly into Grid Edit mode even if the "Grid Edit" flag is set on the datapage settings. Instead the datapage opens in a list view and items such as checkboxes appear as values yes/no instead of a checkbox.
The datapage is therefore unusable until manually switched to grid edit.
The "grid edit" (or another setting) should allow for the form to open directly into grid edit mode.
This is basic and standard UI functionality so very surprised that it is missing or that the "grid edit" flag bug has not yet been fixed.
