There’s been a problem with my IPTV service. On my fire stick app (IPTV Smarters) I clicked the “Refresh DNS” button and that fixed the issue.

However on my iPhone/iPad apps there’s no equivalent button.

Any suggestions for a solution?

(Maybe it’s related - but when I log in on a Fire Stick I just enter username & Password on iOS devices I need to enter a URL as well as username & p/w)
