Have to enter username and password everytime in android app

[DeletedUser]

I am using latest version of grepolis android app in my samsung galaxy s5. It was working fine but after I uninstalled it and reinstalled it, I have to enter my username and password everytime I open the app. It doesn't save the login details. Once I open the app, I have two options: play as new player or login. So I click login and then I have to enter my username and password, everytime. This is tedious.

app version: 2.101.0
