I have read many posts talking about issues wirh pi4 and LE10, but if instead for you it's working, then why not giving it a try?
It's an attempt I can do.
I do not have a spare SD so I am backing it up (dd'ing) and once I am done, I will do a scratch install - anyway I don't think I am going to play with LE9 anymore....
Thanks for your hint, I will play with it and report my findings.
BTW, can I ise TVH 4.3.3 instead of 4.3.2 under LE10? I understood the "unstable" version of TVH is much more up-to-date but LE9 doesn't let me chose it.
