Spotify embedded follow button is not working

[popcultr]

My Question or Issue

My spotify embedded follow button seems to open spotify and then (without following) immediately opens google chrome with a message that says "You are logged in. This window should automatically close in a few seconds. If not, please close it manually." 

I have it embedded on a google sites website and I am trying to test it on my iphone XS IOS 14.5.1. it also did the same on both of my roommates iphones.

pls let me know if anyone has any answers. thanks
