It is cat and mouse, but it has an issue maybe every year or so, and they generally resolve it same day or next day with an app update. The hardest part is generating your own google api keys, but there are straightforward guides and you just need to do it once.
The upside? No ads at all, sponsorblock integration, and an easy 10ft interface that works great with a remote. No shitty web site to navigate with a mouse. Just a list of your videos each day. Click and play.
I cant speak to your overheating issues. I have kodi running on 4gb raspi 5s with the default case/fan. No problems. An external usb fan might help you out. I’ve used one of these with a raspi in the past. Its roughly the same size as the raspi, but dead silent. Moves insane air.
Yup, that’s the one. The sponsorblock app integrates directly with the youtube app. I don’t recall any config at all. Its made by siku2.
I’ve had the youtube app crash, but its infrequent and mainly seems to have something to do with it starting a new video without stopping a currently playing one.
