Didn’t find the option on chromecast hd (android 12). It’s not on the same location like chromecast 4k (android 10). In android 10, you will find under Privacy > Security & Restrictions > Unknown Sources.
But in chromecast hd (android 12), it’s not there.
So if someone can help me.
Thanks !
I had the same issue until I read all the comments and even though I had just completed a factory reset, I went for it again the long way using the remote (instead of your phone.) Set up, Developer Mode, Install IP Vanish, Install Downloader, Auto promts with toggle to ALLOW UNKNOWN SOURCES. Give that a toggle. Enter the code for Kodi on the Downloader Apk app, add the Crew Nich Build, add the task killer code to install on the Downloader app and whatever else your heart desires. I used several pages on Troypoint site to achieve this and obtain the needed codes. I hope this helps. I'm a novice.
