Use the In-Built Browser Smartly :

Many users ignore the SnapTube built-in browser but it's actually super helpfull. If a site is not supported directly by SnapTube try opening it through the app's browser. Play the video there and SnapTube might auto-detect it for download. It’s a trick that works for lot of tricky sites.

Try Using Video URL Method :

If SnapTube says “not supported” just copy the video link from that site and paste it inside SnapTube search bar. Some sites don’t show direct download but this method can still let you grab the video. It works better when the video is public and not behind logins.

Update SnapTube Regularly :

Many times a site is not supported only because you are using an old version of SnapTube. Always check for latest update of the app. The newer version may add support for more platforms. A small update can make a big difference in compatibilty.:

Use Third-Party Site As a Bridge :

There are some websites like “SaveFrom” or “KeepVid” that help convert links to downloadable form. Copy the unsupported site's video link go to such a site using SnapTube’s browser and you might be able to download it from there with SnapTube's help.

Enable Pop-Up & Permissions:

SnapTube sometimes need extra permissions to detect certain videos. Make sure your app settings allow pop-up windows and media access. Also if you use VPN try turning it off. These small settings can help SnapTube capture videos even from sites it says are not supported.
