The very BIG PROBLEM is related to TCL 65" miniled smarttv (but the same was on 55c725 qled before I switched to this miniled ).. the app won't autostart (tried also with the work around for AndridTV found here).
Also tried to use IPVANISH, CYBERGHOST, PUREVPN.. APK but won't autostart if I enable the feature if present (no problems on other ANDROID TV devices if some autostart feature is present ..so also VPN CLIENT PRO).
Today I've tried to purchase (using 7 days trial) some VPN CLIENT PRO feature under licence ( wireguard client, connection on demand, automatic connect..) but stil doesn't start
But..
IPVSNISH and VPN CLIENT PRO apk are much more stable and once manually connected does not disconnect (can happen, but it's not a "plague" because don't always disconnect after some second once I close the apk.
And..
I'm absolutely sure (now!) that this problem can be completely solved. This because I've tried using Internet Private Connection VPN (APK) with the account purchased by a friend of mine and it SIMPLY WORKS!
For some reason can't always connect at the system start, but never disconnect.. once connected you can do everything and VPN still on.
Maybe that workaround in "Always-on-VPN" 3d was related to some previous version of VPN CLIENT PRO ? Because some step are not equal/present..
p.s.
the VPN CLIENT PRO (1.01.53) problem (on TCL smartTV) can be the feature "start on demand monitor" .. that can be started only manually ?
