 ## Current solutions
 
 - dyn-skip
-  - When ads play this instantly notifies Twitch that ads were watched. It then refreshes the stream (either full reload, or using FZZ extension).
-  - May potentially result in multiple refreshes if ads are being served aggressively.
-- dyn-skip-min
-  - dyn-skip variant which doesn't require a reload (WIP/experimental)
-- dyn
-  - Ad segments are replaced by a low resolution stream segments (on a m3u8 level).
-  - Skips 2-3 seconds when switching to the live stream.
-  - Stuttering and looping of segments often occur (during the ad segments).
-  - **NOTE: Removing segments doesn't notify Twitch that ads were watched (aka more served ads).**
+  - Notifies Twitch that ads were watched before requesting the main live stream.
+  - May slightly slow down loading of streams.
+  - Falls back to mute-black if this fails (use an alternative solution if it always fails for you, as it adds additional load).
 - dyn-video-swap
   - Ads are replaced by a low resolution stream for the duration of the ad.
   - Similar to `dyn`, but skips closer to 20 seconds when switching to the live stream.
   - You might see tiny bits of the ad.
   - Audio controls wont work whilst the ad is playing.
