twitter questions

iOS & iPadOS

hi all, when i use twitteriffic for my iphone, i am clearing up my following list. yet, when i have supposedly, unfollowed an individual and i use the refresh command with 3 fingers the entries are still on my timeline. any hints please? i'm just trying to declutter twitter to make it a more enjoyable experience. i use ios 11,2 and an iphone 7. is indeed twitteriffic still the best client on the iphone, and consiquently yoru on the mac platform?
