Friend activity isn't showing on iPhone

[thagoverment]

For some reason it says there's no recent activity when I'm on my phone, but on my computer I can see my friend's activity. Anyone else has this same problem?

btw what is the best way to look for someone's spotify account? other than them having to link it to you

love this app but somethings are frustrarting, like how in a collabrative playlist you cant go into other's accounts
