I'm able login to my account from desktop or mobile browser but the app won't allow me to login.
I'm hoping you would already know my device & OS information if not I'm using LG G6 which runs obviously on Android.
Are you still having difficulty logging into the My Account app?
Hey there @Punnyabrata!
That doesn't sound normal at all, can you try to uninstall and reinstall the app?
Keep us posted if it works or not!
