Mobile CRM app has right Date and tasks due, but wrong day.

Mobile CRM app has right Date and tasks due, but wrong day.

It is Monday Feb 5, 2018 and my desktop is on track with that, but the Mobile app (which I uninstalled and reinstalled to try to correct) has always been a day behind. It claims today is Sunday Feb 5, 2018 basically. I thought this was a timezone or calendar issue but have not been able to correct it. Everything else seems to be working, but this has been a problem since I signed up a couple weeks ago.
