Might want to look into a password manager such as MyKi. I use it on my iPhone and have on my Android since I use different passwords for everything and long 20 digit ones as well. It also does NOT store server side so the companies don’t control your passwords...
I use Weather Forecast Pro. I was able to ignore it before like I said. I find it odd they removed that option in Android 9 to ignore certain applications.
I noticed with Android 9 my weather application keeps popping up with high usage. I don't see a way to ignore this and whitelist it to run like you could in Android 8. What gives. They removed the ability to ignore applications in Android 9?
