Get DateTime Android Bug ?

Hello,

I would like to create a daily reward, and for that I need the compare DateTime. On the Unity Editor, that's works PERFECTLY, but when I export my apps into Android the code stuck with the "Parse" method

I've created a Textbox to understand when the code stop to works : 'DebugText'

 void Start()
     {  
             DebugText.text = "Debug " + DateTime.Now.ToString("dd/MM/yyyy");
             DateTime todaysDate = DateTime.Parse(DateTime.Now.ToString("dd/MM/yyyy"));
             DebugText.text = "Debug " + "TodayOK : ";
     }

As result I have only "29/05/2020", and not "TodayOK" and all code after that are not played. I've tried with

 DateTime todaysDate = Convert.ToDateTime(DateTime.Now.ToString("dd/MM/yyyy"));

But same result

Do you known if there is a specific way with Android to convert DateTime ? I really don't understand because on unity editor my entire code works perfectly :/

Thanks for your tips. Best Regards
