Specify a model-driven app default view
Unless someone has 'pinned' a different view in your app as their personal default, they will see the default view specified by the app maker. Any of the public views can be set as the default view for a table.
Sign in to Power Apps.
Select Solutions on the left navigation pane where the table is located.
Open the table, and then select the Views tab.
Select More commands
next to the view, and then select Set as default view. This can also be set on the command bar.
Set the default view for a table in solution explorer
Open solution explorer, expand Entities, select the table that you want, and then select Views.
Select one of the public views.
On the menu bar, select More Actions > Set Default.

On the solution explorer toolbar, select Publish All Customizations.
