Hi, I am trying to create a simple approval workflow that would also update the status in my library (pending, approved declined - check my screenshot). The update item action works just fine, however notifications are not working, not for the send notification action nor for request approval. I tried several options to put in who to send notification, I've even put in the e-mail manually and it's still not sending any notifications. 

Does anyone have any suggestions?

Thanks in advance for helping a young beginner.

Cheers
