GUID / SSL Issue for remote user swapping from AndroidTV to Unified client on CCwGTV 4K.

[vaise 340]

I did this years back and after a few niggles back and forth, its o=been over a year stable on the unified client - but all my TV's are on my LAN.

I commented to a friend that he was transcoding something I do not, and after comparing the playback settings, decided that he should try the unified client instead.

So he installed the androidTV, then installed the Emby for Android.

After config, he then got a full blue screen saying 'Unrecognised GUID format'

An AI search said this was die to cache stuff being left behind, so he cleared all that n the client, and I cleared the device on the server.

Then he gets a message about the ssl cert, and after clicking OK on that, he gets the guid error again.

Any ideas here ?  The poor guy is recovering from hospital and really needs his access to emby.

Screenshots are attached.

This is why it was not direct playing from the logs -

This is the GUID log issue in the logs I believe -
