Spotify premium version without adverts was launched according to the wish of most of the users because no one wants to be interrupted by annoying ads when listening to music. Unfortunately, Spotify has recently removed the function that allows users to upgrade to Spotify Premium directly from their mobile app.
Upgrade to Spotify Premium is not allowed on the app.
This means that if you want to upgrade to Spotify premium, you will need to visit the actual Spotify website and provide your card details.
It is somehow inconvenient for Spotify members to visit the Spotify website to listen to their favorite songs because the Spotify Premium version is not available in the app. But be happy because you can save your money.
A basic Spotify Premium costs you $9.99 per month (on their website). If Spotify were to allow its users to upgrade to premium on the app, 30% of the payment you make for the service would directly go to the App Store. And this means that you would have to pay £12.99.
You could save $3 per month thanks to that
If you want to use the most outstanding features of Spotify, you will have to visit the Spotify premium webpage to upgrade.
