Im using a simple Login And Signup Page in my app and using Realtime Database to store my users data. It works when I create a new user and then log them in, but when I exit the app open it again and log into the same user, it doesnt work. I tested it by checking to see if the tags Firebase is getting is correct, and it is. I dont know why and I need help
You cannot use an email address as a tag due to the special characters it contains - I am surprised you have not received an error message from Firebase about this.
I have used simple names such as Test or Carl as the email and that works storing it into the Firebase
It could be that Firebase is returning your data with extra double quotes, check the contents of value
being returned from Firebase....
Perhaps this might help:
