The attached image is is what I see when my smartphone in portrait position.
I can see all the fields when in landscape position.
On the web app, when I restrict the frame of the browser, all the field restrict accordingly.
Not on the mobile app
It happens only when all the DOW are selected and the corresponding field shows them.
I think is only a matter to shorten the Monday, Tuesday, …, Sunday strings to Mon, Tue, … Sun.
It should work also in foreign languages, I suppose.
