Is it normal for All custom fields to display on front of card in the mobile app when not on desktop

[Eric Parish]

I chose for certain custom fields not to show on front of card on desktop and it works fine.

However, all of the custom fields show on front of the card in the mobile app.

Is this normal? Because that would mean that should we use the limit of 50 custom fields (per description), all of them would show up on front of the card in the mobile app and would take up a lot of real estate on the screen.

Thanks in advance!
