@tryfresh Hi. Cannot reproduce. Is it caused by one of filters or maybe by stealth mode?
Screenshot:

There are 4 advertisements in one video.
The first ad is removed properly.
When the second ad starts, the black screen appears due to stealth mode.
When the third and fourth ads start, it appears due to ad blocking(adguard base, easylist...).
You should see 4 yellow ad signs like this, but your screenshot doesn't.
r u a laftel membership member?!
If you can't see the ads,
you need to sign up as a new member at https://laftel.net/auth/select
If you can't see it after using this method,
You need to install vpn and set the region to South Korea. Because it is a Korean site.
Perhaps this will be a pretty tough adventure.
If translation is required, please take a screenshot.
Registered. Ads are blocked without issues.
Instead midrolls - ~1 second break.
