I love m3u4u.com

I believe they are all going to have playlist updates and formatting issues.

Honestly though, these days there's almost no need to use such services, since many applications can make the changes in their app with favorites or hiding categories etc.

What exactly are you trying to do?

Also, I wouldn't want to subscribe to such a service at this time since some providers are removing m3u

Just my opinion though, and others may have their own as well!
