UC bug after finishing battle

I got several times now the bug that I get a black screen after finishing my UC fight. Nothing happens. Connect to sever is not shown and game will remain with a black screen. Waited already very long to see if still something happens
Before I have recognized that connect to server does take a huge amount of time until.the actual battle is starting. My wifi is fine. It feels like the servers are too busy. May you check that @Dev_VKC

Me too
