Best asking the developers of the extension(s) you use.
it could be something obscure like the API that serves the extension provided by the developer is blocking you and that is the fall over point.
Either way, they know their own extension better than I do, so I can only guess at the possibles, and they’d know for sure. And this isn’t Streamelements support
Common issues could be
- Cloudflare firewall done screwed up and SE’s API is behind cloudflare,
- SE is blocking you, just you,
- You are using Brave and the extension uses localstorage (hence it works on your phone),
- You adblocked something and it’s stopping it appear,
- Another browser extension is doing something it shouldn’t, try incognito to see or disable everything, that privacy browser extension you have is probably not doing anything useful, if you have a privacy
Aside from that, ask SE, they have more information about their extension and issues they may have than this forum will.
SE can go check their API and/or access/error logs, this forum can’t do that.
