You can try signing out and in again. and that won't work, you can always try reinstalling.
Here's how you do it:
Logging out and logging back in
To do so, go to your “More” menu and select "Sign Out".
To log back in simply enter the email and password with which you registered, and you will automatically be logged in.
If you can't remember which account you used to register, please type in the email address you are using to receive email alerts from Seeking Alpha with.
If you forgot your password you can always recover it by entering your email address and on the password screen tap on “Forgot Password”. You will get an email from Seeking Alpha with a One-Click Setup link. This will log you back in.
If it's not working, you can uninstalling and reinstalling the app.
Please let me know if the issue persists after performing these two measures.
