works great, but as others have said, the profile picture does not currently update correctly. Everything else works and the UI and UX are very good

Awesome extension, only flaw is that the profile picture doesn't get updated when adding a custom image for it.

I love the tool but my channel logo is not showing up on the preview, it just shows the one for the original video. How can i fix this? or is it a problem with the tool?

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
PrevYou — YouTube Thumbnail Previewer does not require any sensitive permissions.

Risk likelihood
Risk likelihood measures the probability that a Chrome extension may turn malicious.
This is determined by the publisher and the Chrome extension reputation on
Chrome Web Store, the amount of time the Chrome extension has been
around, and other signals about the
Chrome extension. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Chrome extension.
PrevYou — YouTube Thumbnail Previewer has earned a fairly good reputation and likely can be trusted.
