The thing is that in the 1.16.0.67 changelog it said that they fixed sign in errors for android and ios but when I try to sign in then It always says that failed to sign in, even when I was online. I uninstalled minecraft, installed it again and then tried again but I still was'nt able to sign in.
Thank you for your report!
