No, there is no reason to panic. However, it is doubtful things will ever be 'fine' as the past couple of years have shown. IPTV with many providers is best described as 'iffy' and that just seems to be the way it is. Seemingly, providers with smaller channel line ups are better able to keep up with server issues such as streams working and on the appropriately labeled channel.
I would rate this service as OK. There are better providers out there but there are also much worse. Seems like the bigger a service becomes, they pretty much seal their own fate.
On the plus side, at least now there is the option of a playlist, so an m3u can be tailored to include just streams you prefer and you can include streams from more than one provider. That way when one doesn't work you can select the stream from an alternate source. This works best for me, rather than using many different addons. And if you take the time to set up your EPG, it all becomes very 'acceptable' for what it is.
Cheers.
