Add a confirmation message if a form is already filled

[jacopo_spinelli]

Hello everyone,
I need some support to setup a specific funtion in my app.
I have a form which is supposed to be filled only once a day, therefore I would like to add a confirmation message in case the form is already filled, the user should see “form already filled today, do you want to continue?”.
The app structure is the following: menu is a gallery view, clicking on the icons we are redirected to the form view using an App LINK. I tried by myself first creating an action with condition “if this is true” IN(TODAY(), TableName[Date]), then the action itself should redirect to the form if action is confirmed otherwise should show the menu.
It’s somehow working even if the confirmation message lenght is cutting the full text (only a couple of words are shown, any clue?), my last problem is, how can I link the action to the Menu (gallery) in the way that clicking on the icon if condition is false-> go directly to the form, if condition is true-> show confirmation message.
Thanks a lot.
