Cancelled Premium Account but Still Avaiable on Mobile App and NOT BEING CHARGED

[leoncios]

I cancelled my Spotify Premium account on my laptop (my three month trial ended 8/4/2017) however I still have premium on my phone and am not getting charged for it. Obviously I'm not complaining, I'm planning to join a family plan with my cousin, but I just wanted to know if anyone else was dealing with this issue? I have the confirmation email and on the overview it says I'm no longer a premium user, yet my mobile app is still premium and I have not been charged for 8/4.
