Apps say "bad password" for good password
I found an "interesting" solution to the problem. When I create a password, I enter it into a password protected document. I have been copying and pasting the passwords, so there is no issue of entering different passwords between the Android and Windows logins or mistyping them. As an experiment, I used the "Forgot Password" function in the Android apps. Then I pasted the exact same passwords I've been using and "changed" the passwords in the Android apps. Now I can log in using the same passwords and don't get the "Bad Password" error in the Android apps, and can still log in the Windows version. This worked for both apps that were having the issues. Go figure. Still haven't figured out why, especially why the mail app that had been working suddenly stopped.
