I think the VLAN stream is only available through the 1.0 app.

Before upgrading the firmware the 1.0 Unifi TV app (2.2.8.0) will auto logout your account when you launch it. You can disable Wi-Fi and use VLAN (IPTV STB mode) to log back in and continue watching as-is. Keep in mind there will be no Internet access so all others apps won't function and cannot update.

After upgrading VLAN won't be watchable anymore. Your account will be fully migrated and cannot log back into the 1.0 app regardless (invalid username/password).

New apps auto installed after the restart: Vidio, WeTV, Blacknut, Prime Video, Youku, YuppTV, Sun NXT. I already installed Unifi TV 2.0 (Unifi TV CL) beforehand. The 1.0 version is no longer a system app.

In terms of bugs feels like overall it is more sluggish even outside of the 2.0 launcher. Video and audio also noticeable offsync (no setting changed). My TV missing option to ignore HDR and the box setting cannot properly disable HDR.

Upgrade process received SMS around 4PM. On the same night 2.0 app still not usable. The following evening only received confirmation.

Only then HP43A box (2/32GB) finally received firmware update. Download size is 1.21 GB.

Their triple-play meaning has changed, landline VoIP replaced with Unifi Mobile. TV now sharing the same bandwidth with regular Internet with recent speculating event VLAN being heavy heartedly discontinued.

If someone still have 1 account not yet migrated to 2.0, can try installing the 1.0 app to the new firmware and confirm whether VLAN IPTV is still available?
