Idk, all I know is that I don't have NewPipe installed and when someone shared a PeerTube link in Lemmy the other day, Tubular opened it with no problems.

i have tagged all the extra links it offered

Is this in the app settings or the device settings?

I didn't know, so I asked Microsoft Copilot:

Tubular, which is a fork of NewPipe, does implement SponsorBlock1. It also supports ad-free versions of platforms like SoundCloud, Bandcamp, and PeerTube2. This means that you should be able to use SponsorBlock with PeerTube videos through Tubular. However, it’s important to note that there has been a discussion about the lack of PeerTube support in the SponsorBlock repository itself3, which suggests that while Tubular supports PeerTube, there might be some limitations or ongoing development regarding full integration. For the most up-to-date information, you may want to check the latest updates on Tubular’s GitHub page or the SponsorBlock issue tracker13.
