Platform not showing in SAP AppGyver

When opening the SAP Appgyver the app closes on by itself or it turn all white with no response. My Composer id is 402011

I hope you can help me with this problem.

Best regards. Apparently it is a global problem, every few minutes and even hours it stops working, and then the problem is fixed. Already the community and even sent a notice to support. Just have a little patience that they’re going to make it better.
