App will NOT log me back after uninstall/reinstall.

Due to another issue I had to uninstall and reinstall the app, as I have had to do it before knowing that I have my king.com connected to my app I was a concerned. But now it will not connect with my email and password, it keeps saying it is incorrect but I am in HERE, it is not incorrect. I have done everything support has told me to do nothing will work. Please tell me there is an answer I miss my game and I was so far 😣
