Hi! I see you're having trouble loading your playlist on the IPTVX app, correct? Just to get a better idea, could you tell me if the playlist was previously working and suddenly stopped, or if this is the first time you’re adding it? Also, are you entering a URL playlist, or a local file? Any error messages showing up?

Meanwhile, here’s a general step-by-step checklist for playlist loading issues on macOS (OS X 10.15.7) with IPTVX:

1. Check Network Connection
Make sure your Mac is connected to a stable internet source. Try loading a regular website to confirm connectivity.

2. Verify Playlist URL or File
- If it’s a URL, please double-check the link for typos or expired credentials if it requires login details.
- If it’s a file, ensure it’s in the correct format supported by IPTVX (usually .m3u).

3. Update the IPTVX App
Confirm that you are running the latest version of IPTVX for macOS. Updates often patch bugs affecting playlist loading.

4. Restart the App and Mac
Quit the IPTVX app completely and restart your Mac. This can clear temporary glitches.

5. Clear App Cache
While macOS apps often manage caches automatically, you can try removing caches manually by going to ~/Library/Caches and finding the IPTVX folder to delete or rename it, then relaunch the app.

6. Modify User-Agent Settings
Some IPTV apps require a specific user-agent string to properly access playlists. While I don't have IPTVX-specific instructions, setting user-agent to something like “VLC” may help in similar apps.

If after these steps you still cannot load the playlist, please let me know any error codes or messages you get, and whether the problem is specific to one playlist or all. That will help me guide you further! Would you like me to walk you through any of these steps in detail?
