I had thought this too about the buzz having compatibility issues with papiao servers, and I experienced the same thing a few times as others , and still am.
But this exact same issue arose a few times over the years, the first time was when we supported them Avov boxes way back in 1914 or something like that

Lots of reports about this same thing then back then, and everyone had Avovs, the thing was though that was exactly true, everyone did have Avovs (including myself) and not many other devices were used (other then kodi apps). So stands to reason most all reports were from avov owners.
There have been at least 2 other times this has happened, so from my memory this will be the 4th time.
This time around members with many Buzz devices, two dreamlink devices, one Formuler device, a few avov devices and there was one report with a mag device, all with the issue.
Most members own Buzz devices these days, so with the math that makes sense.
I run an admin code, which means I can use any server portal without changing it at the papioa website, just change it on my device(s). I do see differences with the portals but I do still have issues on all portals with some channels (format not supported).
I can fire up my old dreamlink T1Plus and with that same server credentials all channels work fine.
I can't explain that, but the issue does stem from the server. If it were the buzz devices alone that had a compatibility issue with papiao it would effect all of them buzz devices, which it's not.
I have ran a B5 here on papiao for a few months some time ago and no issues.
Now I run a couple X5's and a P6 and I do see issues, but them issues change almost daily.
My admin code may have something to do with that, as compared to a normal client code, but I don't know. I am pretty sure its a server issue related to ISP or geo or MACs or something along them lines. Some have rebooted their MAC a papiao or changed portals and seems that fixed their issue, which I know Coyote saw that though so I am not saying anything surprising here.
I also know all this is confussing as heck, and I don't have any answers, just experiences.
Papiao told me again to reboot everything
