Not much help, I know, but I was following some YouTube channels on the Feedly RSS reader because it seemed to get me fewer ads, and the same thing happened there a couple of weeks ago
error 153 everywhere. Maybe it’s YouTube moving the goalposts?
I have tried those too and it works for me. I’m on the Android version of Obsidian, if that helps. I will try it later on the computer to see what happens.
I’ve got the same problem, when I try to make an iframe with a youtube link it says error 153.
Some of my friend does not have this problem, I am the only one. If you managed to solve this problem please let me know how. I tired bunch of things like deliteng the cache, or disabiliting the youtube ad blocker but nothing.
