I have the exact same issue on my 4k+ on the latest release (never tried older release).
I’ll try to create some log files soon. Here some more info:
I reinstalled the latest April update on my Vero 4k+ via the installer
I installed only some basic addons (osmc skin addons, subtitle providers)
LG OLED 55C7V
Denon X1400H (connected to tv via arc)
Apple TV 4K (connected to receiver)
Vero 4K+ (connected to receiver)
Vero 4K+ wakes up from suspend mode when watching tv or using the apple tv
Vero 4K+ wakes up when switching from watching tv to apple tv (turn on apple tv). Most of the time the Vero pops up and I have to select Apple tv again on the input select of the tv/receiver
Vero 4K+ seems (not sure) not always to go to suspend after period of time, i have set this in kodi under power settings. Could be related to the issue above since I just notice from time to time that the red light is not on anymore when I check it.
The same thing has happened to me for a long time. I went through the December update and it happens to me with this new one. Thank God that the vero is put on the screen in black after a while if it is not used. Otherwise, I would have burned my OLED panel.
I think we need to have some timelines when it happens so that we can link it to the log files.
Also maybe it makes sense to wait for the fix that avoids the suspend mode not working due to repeat key press. So my suggestion is we pick this up after the new version released in the coming days.
