Multiple issues w/ app

[Rob-Bork]

Ok, so i made a new account so i could change my username - new email and everything. Upon logging in and confirming the email etc., I noticed that I only have three buttons on the bottom instead of the five i saw on my older account(see picture). This is not my only problem. When I click my account button on the top left, instead of going to my actual account, I am instead shown my liked songs and artists. Not only this, but if I want ro send someone my username, I have to look up my account info on the website just so I can copy a string of numbers and letters. I've given it time. I've searched for other related problems. I have had enough. I am seriously at my breaking point because of how annoyed I am. Please, please help me. (Most recent update for Android is used)
