email problem

Hi, I've had One Calendar Premium for years and it has worked just fine.

I have just bought a new computer (Microsoft) and uploaded the app One Calendar. The problem is the calendar is empty. I tried to enter one of my emails (jjhakan@gmail.com or joellejohansson69@gmail.com) but the app doesn't recognise either. As I've had One Calendar for years, I'm not sure which email address I used. Can you find it for me?

The app still works on my Android phone.

My name is Joëlle Johansson. Tel nr +33669470130.

Thanks in advance. Best regards,

Joëlle
