Mobile View of Calendar: Where Can We Control This?

I have multiple clients who use their URL on their phones instead of the App. All are using CRM 2017. The Calendar view for "My Desk" allows them to look at today or the week. If they opt for the week (and they all opt for the week) you can't actually see what day the activity is on. It makes it quite useless.

My question is where do we get to the calendar screen? I looked under Communications in the Admin section. I switched it to iPhone screens but I am still unable to control making the date visible. I've tried all the screens and even though the Scheduled Date field is listed (on Lists and Grids as well as screens) it is not displaying the date. I have tried turning the GIF off thinking this would do it. Nothing.

What am I doing wrong? Where do we control what is displayed on the mobile My Desk screen?
