Sorry for late reply.
The first post surprised me because mySkip doesn't work like that, it just searches for the skip / banner button and clicks it.
Glad you have checked it has nothing to do with the addon.

@Aroo4x4 This addon doesn't block nor skip any unskippeable ad. It just skip the famous 5 seconds ads at the moment it pops, without waiting, same with banner ads at the bottom of the video.
The reason behind this is that content creators still get monetization when you watch the video, because the ad pops up but it automatically disapears (except when it's the unskippeable one).
As it's OpenSource, you can take a look at the code.
