RPi4 & Nightly

I'm continuing my quest to move from RPi3 to RPi4. I'm using the nightly LibreELEC-RPi4.arm-11.0-nightly-20220315-8dd01e5.img.gz sometimes the Pi will boot others it won't, even though I've waited 15 minutes for it to do so. I've tried with TV turned on, TV turned off. NO difference.

Any suggestions?

Thanks for the suggestion - "unfortunately" today its working properly. I might even have figured out how to get the TV's remote working.

On the other hand there are days when I think the best solution to a computer is a large hammer!!!!
