Empty m3u list after loding url to Gse App

I subscribed AnonFlix. I installed the m3u url to Gse Iptv App. But the channel list is empty.

Hello, did you follow exactly these steps?

GSE IPTV setup (iOS/iPad/iPhone/MAC/Apple TV)

Yes, I followed those steps. I think the problem can be about my m3u url. Can you check the url for validity?

Yes, I send you a DM.
