Description
On the desktop extension you can change the SponsorBlock server to another one on the "Misc" page. I mainly use this to use my own instance to avoid the noise of the official one (or in peculiar case if the main one goes down). Unfortunately seems like there's not an option for that on this app.

We don't plan to support this at this time.
